* The ABC Murders (5 January 1992) – the best one: a delightfully directed and structured tour de force, with an imaginative plot and plenty of fun.
* Dumb Witness (16 March 1997) – her off of The Brittas Empire, a speedboat and Monsieur Bob.
* The Murder of Roger Ackroyd (2 January 2000) – a clever-clever adaptation of Christie’s most ingenious novel.
* Lord Edgware Dies (19 February 2000) – it may cheat, showing you something that doesn’t actually happen, but this is still terrific entertainment. Great characters. Killer twist.
* Evil Under the Sun (20 April 2001) – a devious little plot based on a holiday island. And the last time we see all four main regulars together for ages.
* Five Little Pigs (14 December 2003) – the series is relaunched (fewer regular characters, a new filmic house style) with this POV-twisting flashback tale.
* Death on the Nile (12 April 2004) – a famous story, beautifully adapted with a fun cast.
* After the Funeral (26 March 2006) – the twist is glaringly obvious, but I just didn’t see it.
* Murder on the Orient Express (25 December 2010) – a sombre, thoughtful, pensive version of Poirot’s most famous story. Very moving.
* Curtain: Poirot’s Last Case (13 November 2013) – we waited for 25 years for this episode. It didn’t disappoint.
