London, December 1906. The capital glitters with Christmas lights and festive crowds, yet on Piccadilly something far darker stirs. Beneath Frank Dicksee’s celebrated painting of Romeo and Juliet at the Royal Academy lies the body of a young woman — drowned elsewhere and carefully staged, and with echoes also of Shakespeare’s tragic Ophelia? With Scotland Yard baffled, the Museum Detectives Daniel and Abigail Wilson are called in once more. Drawn into the intertwined worlds of art and theatre, they must unravel a deadly puzzle of illusion and murder before the season of goodwill is shattered by another death.
