80% straightforward 20%obscure , is how I would describe today’s FT solve. Thanks Bradman, for the treat.

A few unknowns but mostly clued well enough to get. Failed to get FLATHEAD but, seeing the explanation with the confusing “see”, I forgive myself. Poor clue imo.
I think 25a needs a different split. “Evil drink maybe” and “(that was) once thought to cause illness?”.
Seeing double in the intro.
22d: the second T comes from caughT, not caT, so no double duty needed.
Agree with Hovis about 25a.
And yet a 3rd possible construct for 25a. I saw it as ‘evil’ being an adjective (as in, appropriately, ‘the demon drink’) and ‘spirit’ as ‘drink possibly’, then the rest as def.
Enjoyed the puzzle anyway, some nice light-bulb moments and I only knew ‘flathead’ as a type screw-driver.
Thanks to Bradman and Turbolegs.
Grant– Coincidentally, Flathead is a lake in Montana as well as a fish and a screwdriver.
@Tony, flathead is also a type of early Ford V-8 motor.
Thanks Bradman and Turbolegs
Still in catch up mode it seems … and found this at a medium difficulty level, taking my average 3/4 hour to get it nutted out across three sittings. A few new words – BUFFS (as soldiers), CARILLON (organ stop), USK (river) and had trouble equating ‘twitching’ to RUFFLING. It also took a while to wonder why KETTERING wasn’t in Kent, even though Kent was a part of the anagram fodder.
Although FLATHEAD was near the end of the solve, once I ignored the ‘See’, it was a gimme – common fish in our Port Phillip Bay and I think the only fish that I’ve even caught there. ‘Flattie tails’ are often served up in pubs here, very sweet and tasty !
Had a bit of trouble untangling EVIL SPIRITS, but ended up down the same line of thinking as Hovis & Andrew.
Finished with REBUFFS (and those unknown soldiers), AGELESS and the tricky BEHELD the last few in.
