In this British mystery, a Scotland Yard detective follows a deadly trail from the Isle of Man to the South of France to solve a movie star's murder.

The glamour of Hollywood has descended upon the Isle of Man. But behind this glossy faade, something sinister stirs. Superintendent Littlejohn thought he was in for a few days' holiday, but when the depraved movie star Hal Vale is found dead in his hotel room, Littlejohn is called to investigate.

As motives and rumors abound, this star-studded pursuit reaches from London and Dublin to the French Riviera. With the help of his old friend, Inspector Dorange of the Sreete at Nice, Littlejohn follows the trail from the sensation headlines to the industry's shadowy tycoons.
