The old Tarleton music hall is the subject of a mysterious building restriction that has kept it closed for more than 90 years. When Robert Fallon is asked to survey the structure, he finds clues indicating that its long twilight sleep may contain a sinister secret. Joining forces with researcher Hilary Bryant, Robert discovers the legend of the Tarleton's ghost, a mysterious figure that was first glimpsed during the era of Toby Chance, a charismatic performer who vanished suddenly and inexplicably in the early 1900s. After almost a century the Tarleton's dark silence is about to end, but there are those who find its reopening a threatening prospect. As Robert and Hilary delve into the macabre history, they both become menaced by the secrets of the past.
