A murder, a mystery house in Lowndes Square, hidden millions, a boy with a limp and a finger print connected to a crime committed 14 years ago - a new mystery is uncovered.

This genuine mystery story takes the reader from one exciting adventure to another with all the adroitness and ingenuity of Mr. Wallace's previous successful books. One is left gasping with suspense as the many clues are unravelled only to be followed by others still more stubborn. A beautiful woman has spent twenty cruel years in prison, for a suspected murder. Her daughter learns of the relationship after a chance visit at the jail. The true facts are known only after the discovery of nefarious plots to kill the daughter, visits to the home of royalty, and enforced stays at a so-called home for mental cases.
