Its favourite afternoon pastime was murder, and its favourite evening occupation was the same, only a trifle more so. Anthony Bathurst reaches Swallowcliffe Hall, summoned by Constance Whittaker, to protect her husband, Major Whittaker, from an unnamed threat. Bathurst enlists his friend Peter Daventry, a crack shot and good in a fight. One of the household suddenly drops dead, despite no one being anywhere near him. When poison is revealed to be the method of execution, Bathurst finds himself asking how someone can poison from a distance, or whether there is quite another solution to this fiendish mystery . . . Invisible Death was originally published in 1929. This new edition includes an introduction by crime fiction historian Steve Barge.
