This is the fourth of five Christie novels I have planned for Halloween Bingo, and the first Tommy and Tuppence novel I've read.
I quite enjoyed it, though Tommy and Tuppence were at bit...much at the beginning. Once things got more serious and down to business they were much more bearable.
I prided myself because I was sure I'd figured out who the big bad was well before the reveal, only to change my mind later on, only to then discover I'd been right to begin with!
