At the heart of these mysteries is Arthur Seymour, a reclusive scientist experimenting with uranium and radium. With a broken engagement and a bitter rivalry with the jeweller, he becomes the prime suspect. The police enlist the help of Sir Henry Fordyce, Seymour's neighbour and our reluctant narrator, to uncover the truth and risk his own life in the process.
First published in 1926, 'Vanishing Men' is a compelling murder mystery that explores the dark side of early 20th-century scientific research.
