Written in 1927, this contains several commonplaces of Golden Age mystery novels: a country manor house party, a seance gone wrong, a locked-room mystery, and a bit of romance. The main characters are Stephen Munro and his former girlfriend, Pauline Mainwaring.
Stephen is a gentleman, but one who no longer has any money, which has compelled him to give up his hopes of marrying Pauline. Instead, Stephen has obtained a position as a footman at the country house of Lady Susan Carey. Awkwardness ensues, as Stephen finds one of the guests is an old school chum who keeps wanting Stephen to be one of the gang rather than a footman, which goes over very badly with Lady Susan’s butler. Another guest is Pauline, inexplicably engaged to an odious London money man.
During a seance, one of the guests, a young woman named Cicely, disappears, and Stephen and Pauline team up to try to find her and figure out what is going on. The books description tells us that this story was first published as a 30-part newspaper serial, and the paper offered a large sum of money to anyone who guessed the solution. Agatha Christie herself entered and couldn’t solve it. All I can say is that I’m not at all surprised that the paper offered the reward and nobody won it. The whodunnit is solved by Stephen by making a story out of very little. It’s still entertaining, but don’t get the idea that the mystery is somehow a fiendishly clever puzzle that only the cleverest person can solve.
As with most Golden Age mysteries, there are some antiquated elements, like Stephen’s insistence that he cannot marry Pauline because he cannot support her in her current style. Of course, nobody even considers what kind of money she might have. Worse, though Pauline’s fiancé is never overtly described as being Jewish, his name and character fit the all-too-common stereotype of Jews in Golden Age mysteries.
Despite some drawbacks, this is an entertaining light period mystery.
