Sparks and Bainbridge of The Right Sort Marriage Bureau return when their expansion into a new office, and acquisition of a new desk, results in unexplainable phenomena that can only mean that their new digs are haunted! In London, 1946, The Right Sort Marriage Agency is off to a good start and their early success means that Miss Iris Sparks and Mrs. Gwendolyn Bainbridge can now afford to expand into the long-empty office across the hall. And, with that long closed office comes some more professional furniture, including a partner's desk from Harrod's. But, something is afoot in that office, strange noises at unusual hours, some of the furniture seeming moved around and cleaned, all behind a locked door. The building's janitor is convinced that this is proof that the office is haunted. But, Sparks and Bainbridge are not so sure that's the only, or even the correct, conclusion. Instead, they suspect there's something going on related to the locked partner's desk and the long closed office. With their detective hats on, Sparks and Bainbridge are determined to uncover the truth about the mystery of the haunted partner's desk...or die trying?
