Elizabeth II’s coronation is looming, but DI Edgar Stephens is busy investigating the death of a local fortune-teller. Meanwhile, his old pal, the magician Max Mephisto, is rehearsing for his television debut, a coronation day variety show. But upon hearing that their wartime commander, Colonel Cartwright, has been found dead in his flat, the two men join forces to find out what happened.
            While Max is stuck in rehearsals, Edgar finds himself heading to New York, hot on the trail of a mesmerist he’s sure has valuable information for them—and his trusty sergeant, Emma, investigates some important leads at home. As the clock ticks down to coronation day, the team must scramble to keep Max’s small-screen debut from ending in a dangerously explosive finale.
