内容简介：
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 - especially as she stood to inherit a large fortune. But Uncle Jonathan had a second secret will and the beneficiary is the wide-eyed, seemingly innocent Mirrie Fields. There is also the puzzle of the missing fingerprint. It was the showpiece of Uncle Jonathan's collection, acquired from a self-confessed murderer...who is still at large. Now the print has been torn from its album and Miss Maud Silver is determined to find out if it provides a clue to the killer's identity.
