For this mystery we're back at a house we've visited before, Chimneys. Lady Ellen 'Bundle' Brent and
her father Lord Caterham are no longer living there, they have rented it to the industrialist Sir Oswald Coote. The Cootes are having a house party (one at which the guests seem better known to each other than to the Cootes) and a guest is found dead in his bed.
Bundle Brent returns to the house, she is a friend of all the guests at the house party, and she decides to investigate. There's no Poirot in this one, but there is Superintendent Battle, who Bundle goes to see for information and advice. I like Superintendent Battle;
What I'll do for you, Lady Ellen, is this. I'll just give you one little hint. And I'm doing it because I never have thought much of the motto 'Safety First'. In my opinion all the people who spend their lives avoiding being run over by buses had much better be run over and put safely out of the way. They're no good.
Another person who was at the house party is killed, and Bundle and her friends are getting drawn into a very dark game.
I always enjoy reading an Agatha Christie novel. I missed Poirot slightly in this one, but a good read all the same.
