The Fingerprint (Miss Silver, #30)

When she found the body of her beloved Uncle Jonathan, Georgina's mind went blank. Instinctively, she stooped to pick up the revolver, thus becoming the prime suspect. For Georgina stood to inherit a large fortune when her uncle died. But Uncle Jonathan had a second secret will and the beneficiary is the wide-eyed, seemingly innocent Mirrie Fields.

But there was also the puzzle of the missing fingerprint. It was the showpiece of Uncle Jonathan's collection and he enjoyed telling the story of how he had acquired it from a self-confessed murderer, who was still at large. When the old man was shot, the print had been torn from its album.

Was the missing fingerprint the clue to the murderer's identity? Maud Silver is determined to find out.
