When Australian novelist Leckie Armytage bought The Plays of Oscar Wilde from a thrift shop she had no idea the luggage key ticket she found in the book would lead her to England in search of a man who vanished off a cruise ship seventy years ago. Supported by Herbert’s grandson, wealthy Albert Stokes and his personal assistant and unspoken love Eugenia Purdie, Armytage, gathering material for a novel, searches the Stokes family archives, uncovering ruinous evidence of illegitimacy, blackmail and murder. True to her threat, Molly’s ghost endangers the trio as they crawl through London’s sewers seeking ingress to a buried basement and Herbert’s missing cabin trunk, which they hope to find there. Will the trio solve the mystery and escape the perilous, crumbling basement before Molly compels Leckie to harm her companions?
