A delightful Sunday puzzle from Italicus that slowly revealed its secret.
The secret being that the crossword has a ghost theme of The Hitchhiker’s Guide to the Galaxy, and subsequent novels, by Douglas Adams. I have read the first book, a long time ago, and I can certainly see a number of references. The one that gave it away was FORTY-TWO, the answer to the Ultimate Question of Life, the Universe, and Everything, found by the super-computer DEEP THOUGHT. GALAXY makes an appearance at 2dn; the last remaining human, Arthur DENT is also there; as is Marvin the Paranoid ANDROID. PUTTY and ARMPIT are to be found in Ode To A Small Lump of Green Putty I Found In My Armpit One Midsummer Morning. MOSTLY HARMLESS is part of the series, as is So Long and Thanks for All the FISH. And Dirk GENTLY was also written by Adams. I’m sure there are more, which aficionados can point us to in the comments section. A fun puzzle, where a lack of knowledge of the theme would have been no hindrance to solving it.

12 10p, say, essentially deducted after large university revel

Many thanks to Italicus for this Sunday’s puzzle.

Enjoyed. Completed at a leisurely pace oblivious to the theme. The blog tidied up the parsing (forty-two, raffish – I thought ‘fishy’ but then I had the ‘y’). LUXURIATE and ARMPIT both funny. I thought of ICE as diamond rocks. Just the right level for a lazy Sunday. Ta.
The ‘diamond’ interpretation of ICE for ‘rocks’ is no doubt what Italicus had in mind, rookie. Thanks for that.
You can’t be a hoopy frood, Pierre, since you didn’t list TOWEL as thematic.
I am lots of things, Hovis, but definitely not one of those. If I knew what it was, I could even tell you whether I would like to be one.
Just as well a knowledge of the novels penned by Mr Adams wasn’t essential although the inclusion of FORTY TWO should have rung a faint bell even with me!
Top clues here were ARMPIT, TOWEL and SHRINK.
Thanks to Italicus and to Pierre for the review, particularly the explanation of 25a which had left me wondering.
Must investigate hoopy froods – sounds ridiculous!
Funnily enough, I too clicked with FORTY-TWO. An odd number (well, an even one actually) to light upon other than to fill a particularly difficult spot or with Adams in mind. I spotted TOWEL which I’d already got but I don’t think I had thought of THOUGHT at that point. I stupidly put it down to a nice coincidence. Doh!
Particular favourites include: ARMPIT, ALARUM, THOUGHT, FISH, MOSTLY, TEMPLATE, HARMLESS and GENTLY. A very pleasant morning solve.
Thanks Italicus and Pierre
Fantastic thanks Italicus and mon Frere Pierre. Loved this as the theme appeared, right up my street.
As Pierre says, a fun puzzle, where a lack of knowledge of the theme would have been no hindrance to solving it. We solved it without knowing the theme but then a few entries, such as FORTY-TWO, DENT and GALAXY looked suspiciously familiar. We’re not into TH-HGTTG but have a nodding acquaintance with it, sufficient to convince us there was a theme.
Favourites were SOLSTICE and EVOLUTION.
Thanks, Italicus and Pierre.
A delightful puzzle. I was in a hurry this morning and solved without twigging the theme, unfortunately, but I’m so glad to see the tribute to Douglas Adams and glad I came here later.
