This charming, excellent whodunit is set in London during the Victorian Era. It has two brilliant main leads, Gerald Witherspoon, a Scotland Yard Inspector, with a Sherlock Holmes reputation for solving the most baffling of cases, and then theres Mrs. Jefferies, a policeman's widow, and the Inspector's housekeeper, who has an interest in solving mysteries. Whenever Inspector Witherspoon is on the case, Mrs. Jefferies isn't far behind, in this particular case, the Inspector is called the murder scene of a doctor who is poisoned. He goes home to tell the sweet old Mrs. Jefferies about his case, so she along with his staff get involved in his Detective business.

A servant girl and a priceless brooch vanish at the same time, and it doesn't take a genius to put two and two together. The Inspector finds the brooch on a dead woman—but where's the missing servant? Fortunately, Mrs. Jeffries isn't one to give up on a case just because of a few loose ends.
