November, 1928. Family and friends have gathered at the Shropshire country home of Penrose Llewellyn to celebrate the retired wealthy businessman’s 60th birthday. But the morning after what should have been a convivial supper party, their host is found dead in his bed – and the circumstances look decidedly suspicious. As he questions the victim’s nearest and dearest, DI Reardon discovers there are several longstanding secrets lurking amongst the Llewellyn clan – and he is convinced that not everyone is telling him the truth, or at least not the whole truth. Those who stand to inherit most from Pen Llewellyn’s will – if it can be found – are under the strongest suspicion, and among them hides a ruthless killer.
