Evil Under the Sun ★★★★

When I was young I went through a phase where I exhaustively read anything by Christie, prompted by Death on the Nile with Ustinov on the cover as Poirot. Every book I read it was Ustinov banging on about grey cells in my mind's eye
This gem has an ensemble cast all killing each other with enough steely eyed banter, wit and downright bitchiness way before any murder has been committed in another sun-soaked haven
