50. Give Me Your Hand by Megan Abbott
Kit’s worked hard to get to the top of her profession, when her old school friend Diane suddenly reappears as a rival.
Kit and Diane were inseparable as teenagers until Diane revealed a terrible secret. And soon Diane knows something that could destroy Kit’s life too.
It’s a fairly average psychological thriller. There’s some seriously bizarre behaviour and reactions from the supporting characters about things they think Diane’s doing.
51. Closed Casket by Sophie Hannah
One of Sophie Hannah’s Poirot books.
I was not impressed.
Poirot and Inspector Catchpool of Scotland Yard are invited to spend a week at Lady Athelinda Playford’s Irish mansion, where she announces over dinner that she’s changed her will to leave everything to her terminally ill secretary. Murder follows, of course, so Poirot must investigate.
It starts out ok, but the characterisations were weak.
Catchpool narrates the book, but after getting to the end of the book, I’ve still got very little feel for his character. He seems to be mainly there so Poirot has someone to chat to, and he has about as much personality as a plank.
Plus he doesn’t seem to be a particularly valuable Scotland Yard detective.
He books a weeks holiday off work, fine. The local police demand everyone sticks around in Ireland until after the victims inquest, fine, his boss might not like it, but there’s not much choice in the matter and they can extend leave from work for that sort of thing.
And then! He calls his boss and says that Hercule Poirot wants him to stick around because Catchpool’s a useful sounding board, and his boss immediately gives him an indefinite leave of absence! Must have been a very slow crime month in London 
Surely a normal reaction from a boss would be more along the lines of “No, Poirot will have to manage without you, you’ve got your own work to do here, I’ll expect to see you at your desk on Monday” ?
The ending was also unconvincing. The killer’s ultimate motive was pretty unbelievable.
It’s probably okay to pass the time with as long as you’ve got low expectations, but I don’t think I’ll bother with any more of Hannah’s Poirot books.
