Death in the Cup - Moray Dalton - Bog

Murder in the poisoned bosom of a genteel, if alarmingly dysfunctional, family in the English countryside.
Dennyford is a "peaceful little place . . . where the most exciting thing that could happen would be the lowering of somebody's golf handicap. . . ." Or so the locals used to think. But young Lucy Rivers is in love with handsome Mark Armour, the local police's chief suspect in a most dreadful murder case - the initial slaying (that of Mark's domineering older sister, Bertha), and another which follows it, appear to have been done by means of arsenic. The true killer is finally unmasked, with credit going to the wily Hermann Glide, working in parallel with Inspector Collier of Scotland Yard.
Death in the Cup was originally published in 1932. This new edition features an introduction by crime fiction historian Curtis Evans.
