Kate Shackleton picks up her second professional sleuthing case in 1922 England. Exposing the culprit of a pawn-shop robbery turns sinister when her investigation takes her to Harrogate, and murder is only one step behind. A night at the theatre should have been just what the doctor ordered, until Kate stumbles across a body in the doorway. The knife sticking out of its chest definitely suggests a killer in the theatre's midst. When a ransom note demands ?1,000 for the safe return of the play's leading lady, the refined streets of Harrogate play host to Kate's skills in piecing together clues-- and luring criminals out of their lairs.
