I read The Suspicions of Mr Whicher a few years ago @DuPainDuVinDuFromage when it was very hyped up and I thought it was... ok, but not as good as all the hype?! Still interesting to hear that Constance lived such a long time afterwards though and never (or presumably never!) told anyone exactly what happened.
I remember loving Labyrinth too @ChessieFL but struggle to remember anything at all about it now, although to be fair having DC in the meantime has turned my brain to mush... Carcassonne was a lovely place to visit for the weekend though (also pre-DC, so I remember some of that!).
The Alex Rider books got me through many a long, interminably dull evening/ night trying to get my DTs to sleep when they were smaller @ICrunchCrispsNotNumbers and @Natsku - they were entertaining and undemanding (the books, not the twin toddlers!). In fact they may be due a re-read now I get more than 4 hours of sleep per night 
I thought the Haunted Hotel looked great @RomanMum - I really like The Woman in White - checked my Kindle and it's been on there for 10 years without me getting round to reading it
hopefully this year!
My list:
1: EC Bateman - Death at the Auction
2: Sophie Irwin - A Lady's Guide to Fortune-Hunting
3: Deanna Raybourn - Night of a Thousand Stars
4: Lynn Messina - A Brazen Curiosity
5: Lynn Messina - A Scandalous Deception
6: Lynn Messina - An Infamous Betrayal

8: Richard Armitage - Geneva (audiobook)
9: Hazel Holt - Death of a Dean
After my frequent moans about Americanisms creeping into supposedly English texts, I thought I'd re-read a Mrs Malory, where a middle-aged widow solves cosy crimes in quintessentially English settings. Lovely, I love a Mrs Malory... except I'd managed to get hold of an American copy somehow. FFS!! Anyhow, always a pleasure to read these except they make me hungry, as everyone's always enjoying tea and cake!
On to Richard Osman - The Bullet that Missed - I thought the first two were pleasant and entertaining enough but have only a vague idea what actually happened. Oh well.
