In this two-part mystery, first a determined and uncompromising young Englishman traveling under the name 'John Walker' arrives in West Africa, on the run from events back home. Soon, he finds himself embroiled in adventure and romance by land and by sea. Meanwhile, in part two, the equally implacable forensic detective Dr. John Thorndyke investigates the theft that provoked 'Walker' to flee England in the first place and soon discovers unexpected mysteries.

Nine more cases of theft and murder for the great "scientific investigator" Dr. John Thorndyke. Including a woman harassed over a Japanese casket of dubious artistic merit; an allegation of murder where the victim has already been cremated; a Suffragist accused of theft and murder; a man found drowned in a ditch, and a woman found with her throat cut; the grizzly contents of a salesman's sample box; a mysterious death and a missing ornament; and a man blown to pieces in an explosion.

In The Red Thumb Mark, the doctor works to clear young Reuben Hornby of stealing a parcel of diamonds from his uncle's safe, despite the apparently damning evidence. Then, in The Eye of Osiris, an amateur Egyptologist abruptly goes missing, leaving behind a strangely vexatious will. In The Mystery of 31 New Inn, Thorndyke's long-time collaborator Dr. Jervis consults his mentor regarding a mystery who may be being slowly poisoned. And in A Silent Witness, someone is making very determined attempts to murder inoffensive newly-qualified Doctor Humphrey Jardine.

The book presents a fascinating 'return of the prodigal' mystery set in the later stages of the Second World War, amidst the close-knit farmerfolk community of Lancashire's lovely Lune valley. The Garths had farmed their fertile acres for generations.
