Several years ago, discovering that the impossible crime novel was a thing, I read Anthony Boucher’s Nine Times Nine (1940), originally published as by H.H. Holmes, and loved it. I then discovered TomCat’s list of favourite impossible crime novels and was intrigued by the fact that, eschewing the accepted classic that Nine Times Nine is, Boucher’s later, less discussed The Case of the Solid Key (1941) was included there instead (TC, it must be said, is something of an iconoclast…). More Boucher followed, some of it disappointing, and last year I finally ran to ground a copy of TCotSK in a secondhand bookshop in Philadelphia and — at long, long last — here we go.
I started 2019 on The Invisible Event by sharing the wonderful news that Goodnight Irene (2018) by James Scott Byrnside was a modern impossible crime novel we had legitimate reason to get excited about. And, excitingly, the end of that book promised a follow-up — titled Nemesis at the time — in 2019. And, one title-change later, no doubt on account of some has-been getting there first, here we are.
For a book set against the backdrop of a play based on one of Agatha Christie’s most famous works, and featuring a detective the front flap tells us is “unparalleled even by Hercule Poirot”, there’s more than a passing whiff of Ngaio Marsh about this one.
