At Pittsburgh's historic Hotel 1911, the Association for Gravestone Studies is stunned when one of their members is strangled to death onsite. The police claim that the hotel's manager, Mr. Fig, is the only one who could have reached the victim's room, but clerk Ivy Nichols believes he is innocent. In this follow-up to Murder at Hotel 1911, the inexplicable appearance of strange drawings, an old book, and a wig lead Ivy to a bizarre connection between the grave-obsessed guests and the murder. When Fig confesses a long-held secret, though, Ivy fears she has put herself in the sights of not only the murderer but another dangerous criminal, too.
