Suddenly at His Residence by Christianna Brand was first published in 1946 but it was reprinted by British Library in 2023. It’s an Inspector Cockrill mystery. It’s subtitled A Mystery in Kent, but really it could have been anywhere in the south of England. In Americal this book is titled The Crooked Wreath.

The setting is Swanswater Manor, a large house owned by Sir Richard March. As World War 2 is still ongoing the manor is fuller than usual, Sir Richard’s family has gathered together, including his grandchildren. After the death of his wife Serafita Sir Richard had married his long-term mistress Bella, who had had a daughter by him, and she had had a son Edward. He’s an attention seeker and has concocted mental health issues which might come back to bite him.

The whole manor house is a shrine to the first wife Serafita, there are portraits of her everywhere, and small tables with her ballet shoes and other personal things on show, it’s a cross that Bella has to bear.  Sir Richard is cantankerous and uses his wealth to manipulate his family, he’s always changing his will, despite the fact that he has a weak heart and could pop off at any time.

This is an enjoyable classic country house mystery, although I did guess who the culprit was, but not too early on.

There’s an interesting introduction by Martin Edwards.
