BROKEN MUSIC, by Marjorie Eccles
Reardon soon discovers there are plenty of secrets still being held close. But do they have to do with the first death? Then a maid at the big house is murdered, and Reardon is convinced the two deaths are connected. Compelling, convoluted, with a cataclysmic (had to keep the c's going) ending, it's a keenly-detailed observation of the devastation that the war brought to Britain..
