## Inquisitor 1265: A-trocity by Shark

Posted by duncanshiell on January 30th, 2013

Shark has set a number of Inquisitor puzzles and each has been very satisfying.  I blogged one focused on Socrates and his comment that he didn’t know there were so many things he could do without.  Having glanced at many catalogues and websites over the Christmas period, I can tell him that nothing has changed.

For this puzzle we were told that "the grid is a re-enactment of a famous event.  Down clues are listed in alphabetical order of answer, several pairs of which require identical thematic treatment before solving.  Half of the bars have been removed and these must not be included in the final grid.  Two groups of letters also need removing, the total number relating to the date of this event.  The first is a two-word object.  The second comprises a place plus the outline of a thematic shape.  Only real words must appear in the final grid if spaces are ignored.  Finally solvers must highlight who might have remained after the event (9 letters).  Two answers are confirmed in the Oxford Dictionary of English.

Clearly there is a lot going on here.  There are no clue numbers nor are there any indications where the entries are to be placed.  There is therefore a significant jigsaw element to the puzzle involving the location of bars as well as the positioning of the clue answers.  Finally we have to amend a number of pairs of down clues before we can solve them.  At least we are told the lengths of the entries!

A quick glance at the across clue lengths, confirms my initial suspicion that the grid is not symmetric.

My strategy for solving a puzzle like this is to create a grid in Excel so that I can experiment with fitting answers and I can erase errors with ease.  Excel also allows me to add cell borders to form bars.

I got off to a reasonable start as 1 across was obviously going to begin in the top left hand corner.  The clue was a fairly simple anagram for TYLENOL (one of the two entries confirmed by the Oxford Dictionary of English; the other was OPHIR, the second last across clue).

The early across clue lengths suggested to me that there would be two across entries in each of the first three rows.  That same logic broke down in the fourth row.where there was but a single 4 letter across entry in that row.  The first few across clues didn’t seem that difficult so I had GAYER, CARBIDES, SAFE and OHIO fairly quickly.

Given that the title of the puzzle was A-TROCITY there was a good chance that the letter A would play a part in the adjustments to the relevant pairs of Down clues.  Using the letters I had in the acrosses, I looked in the Downs approximately where I would hope to find answers beginning with certain letters.  The first down clues to fall were YAHOO, E-BOOK, NICEST, LENGTHEN and ASTOOP.  All of these could lock into the letters I had for all the acrosses at this stage, so it was worth taking a risk and banging them in.  From two of these Down answers it was clear that some clues were losing an A.  I guessed that HUNGRY in the third down clue was going to gain an A to become HUNGARY.  My first solution to that clue was C (H) AMP, but I had to change my mind when it clearly wasn’t going to fit.   It wasn’t till quite a bit later on, when I understood more about the theme, that I realised that the A[-bomb] was being DROPPED  from one Down clue to the one immediately below.

From this point solving and fitting progressed steadily, although I stalled for a bit in the South West corner where CERO, BURGH and ANALOG took longer to solve and fit than they should have.

Overall this puzzle did not have difficult clues to solve.  The vast majority of clues had wordplay that only involved two constituent parts.  The initial challenge involved the jigsaw nature of the puzzle and the determination of the link between the associated pairs of successive down clues.

The printed grid had 33 bars.  Building up the grid and putting in bars generated another 33 bars (shown in red below) as required by the preamble.  At this point the grid looked like this:

A study of the grid yielded the two words ENOLA GAY (object) in the top row and HIROSHIMA (place) in the bottom row.  It seemed likely then that we would have to create a space shaped liked a MUSHROOM CLOUD to depict the detonation of the Atomic [A] Bomb dropped on HIROSHIMA by the bomber named ENOLA GAY.  I was initially drawn to the letters MUSH in row 8 and the occurrences of OO in a few places in the grid.  However this got me nowhere.  Reading the preamble again reminded me that the grid would only contain real words after the required letters were removed.  Puzzles of this nature generally involve symmetry in the final step.  A bit of experimenting showed that we could create an almost symmetric mushroom cloud shape rising from the ruins of HIROSHIMA by removing 2 letters from each of rows 11, 10 and 9, followed by 4 in row 8, 6 in each of rows 7 and 6, 4 in row 5 and 2 in row 4.  The cloud is symmetric within itself, but it is slightly to the right of centre in the grid [a function of using even lengths of cell spaces when the grid has an odd number of columns).  This removed  28 letters.  There are 8 letters in ENOLA GAY and 9 in HIROSHIMA giving us 45 letters to remove in total.  This reflects the fact the bomb was dropped on 6th August 1945. I had a quick look at the letters removed for the cloud but soon decided that they didn’t spell out a message.  I think it would have  been incredibly impressive if they did.

The real words left across the spaces are TYLER (row 1), EAR-BONE (4), VOLKSLIED (5), OLEARIA (6), SPINOSE (7), HIBAKUSHA (8, more below), RANAS (9), TEN (10), DIRER (11) and OPAL (12).  Going down, the new words created are BURG (column 3), BOOK (4), ICE-SKATE (5), DEARED (6) EN(7), ST(8), ARRAN(9), SUBLUNAR(10) and ROSACE (10)

The final stage of the puzzle is to highlight who might survive after the event.  HIBAKUSHA is a term for a survivor of the 1945 Atomic bombings of HIROSHIMA and Nagasaki..

The final grid, without the extra bars, therefore looked like this.

I think the title A-TROCITY is now self-explanatory given the comments above.

Shark has given us plenty to think about in this tour-de-force of grid construction.  I think he/she has got the balance right between the clue difficulty and the grid fill in this puzzle.  I look forward to more Shark puzzles in the Inquisitor series.

1. Hi of hihoba says:

I finished the whole puzzle and found the plane, bomb-site and survivors. I was thrown at the last hurdle by one word in the rubric. This was the word OUTLINE. I was looking to remove the outline of a mushroom cloud and had got as far as removing the stalk and the base of the mushroom. After that I could see removing single outlining letters to some extent, but it did not quite work properly. Why was this word there at all editor? It is unnecessary and wrong! Duncan has removed the shape, not its outline in his clearly correct and excellent blog.

2. starburst says:

I agree with Hi of hihoba. The preamble HAS to be completely unambiguous for these puzzles to be completed, and again it wasn’t. The word outline clearly suggested to me that the outer section of a shape had to be removed, not the whole shape. There is something intensely frustrating about having completed a grid, only to be stymied by a confusing instruction at the end

3. duncanshiell says:

Hi @ 1 and starburst @ 2

I guess I’m guilty of not reading the preamble properly. I focused on the need to end up with real words, coupled with the fact that most of the ‘new’ bars occurred in the middle of the page, and the likely need to remove a further 28 letters to meet another requirement of the preamble. I just assumed that to get 28 letters we would have to remove the whole cloud.

I can understand your points very clearly though.

4. John Lowe says:

Hi Duncan

I think I can help with the down clue “Paula and Holly almost overtaking crash”. The first a of Paula is removed: P (Pula) + ILE (Holly = ilex, almost) + UP (=overtaking) = PILE-UP.

Thanks for the blog – and to Shark for the Crossword, for which a certain amount of thought was needed to put the puzzle together correctly. I think that the number of squares to remove was the clincher for resolving the outline/shape ambiguity, and the wording of the rubric didn’t disturb me too much. I enjoyed it.

5. HolyGhost says:

I found this pretty tough, but rewarding – at least until very near the end … I spent ages looking for the OUTLINE of a mushroom cloud, and knowing that the relevant date was 06-Aug-1945 didn’t help me at all to guess that I should be looking for a further 28 letters to remove. (I did get there finally by using the “only real words” part of the rubric.)

Whilst agreeing with John Lowe’s wordplay for PILE-UP, I cannot agree with his use of the word “ambiguity” with reference to outline/shake – it’s not ambiguous, it’s just plain wrong! It seems that those of us who read (& trust) the preamble were disadvantaged here.

Thanks, Duncan, for the blog and for letting me know the two entries that are confirmed in the ODE. Does that by chance also have SO = shipping officer (for the SHACKO down clue)? – I couldn’t find it in any of my reference material.

And of course thanks to Shark for a marvellous work-out.

6. Shark says:

Duncan. Thank you for an impressive blog and I am glad you enjoyed albeit at the difficult end of the spectrum (perhaps). I am very grateful for John for publishing it as some may have found the theme rather dark despite it being an important event in history.

Outline is on my shoulders. Sorry for that. It stems from the original preamble I wanted, but it had to be shortened due to allowable space. If you draw bars around the missing words/shape they add up to 45 and so that being an outline. This ensures the shape is unique rather than having to hunt for real words. In reality it is easier to look for real words than count bars, but it may have added confirmation.

To clarify, the preamble had this line:

“This can be resolved by ensuring that all empty cells can be surrounded, excluding the perimeter, by the same number of bars as empty cells”

I must have got fixated on outline, but can see how misleading that could be. Trust me I spent a long time trying to make, what I thought would be a tough puzzle, as fair as could be.

It was a puzzle that was hard to construct. Real words forming and only using half the bars there had to be sacrifices and so the symmetry had to go. I only lose symmetry if only necessary. The clues were made slightly easier than my usual style to balance it out.

Hopefully you will enjoy the next without any feeling of ambiguousness. Shark

7. Rob H says:

Many thanks to Shark for a super puzzle and to Duncan for an excellent blog.

Just one small correction, I think the remaining real word in row 10 should be TENACES as there is no vertical bar after the N in the original grid. Thanks again to both.

8. duncanshiell says:

Holy Ghost @ 6 and Rob H @ 8

I think attention to detail has let me down on both your points – the SO I was looking at in the dictionary was ‘shipping order’ and not ‘shipping officer’. TENACES is the required word. In each case I think I just saw what I wanted to see and moved on.

Thanks also to Shark for dropping in.

9. starburst says:

Thanks for that Shark. The grid itself must, as you say, have been extremely difficult to construct, and for that I salute you

Thanks also to duncan for the blog

10. regalize says:

The clues were ‘made slightly easier’? Thanks Shark! Your teeth bite. This IQ took me a full ten days to get through and I am gratified that Duncan’s blog confirmed I hadn’t gone completely wrong. Usual snores re preramble complaints.

11. HolyGhost says:

What does regalize mean by “Usual snores re preramble complaints”?

12. Bertandjoyce says:

We thought it was a really god puzzle. We did spend some time identifying what had to be removed but looking back on it we concentrated more on identifying proper words whilst also looking for an appropriate shape and weren’t confused by the preamble.

Thanks Duncan for the blog and Shark for a very ingenious and somewhat poignant puzzle.

13. Ross says:

Best puzzle of the year so far (although yesterday’s Woodchuck Puzzle in context might give it a run for its money). I too got troubled by the preamble, but the bars (or absence of bars) was sufficiently helpful to ensure that there could only be one final outcome.

14. starburst says:

regalize

it must be so tedious to have to listen to people making valid points about the preamble. Or preramble as you put it. I may be wrong but the setter himself seems to concede a degree of ambiguity in it, so I’m at a loss why you felt the need to make such a graceless comment

15. Phil Richardson says:

Thanks Duncan for a great blog. And shark for popping in to provide context. Must admit this was a stinker and a stunner in equal measures. A good 5-6 days of torture. I managed to get there but struggled on the wordplay for pile-up and bone. The responses in this blog really help, thanks all. A masterful grid construct.

16. HolyGhost says:

I only just realised (after looking at the published solution) that the A‘s dropped from the nth word of one clue into the nth word of the next – very neat, but lost on most of us.
