During the twenty-four hour period that the five Earths are merged, a detective convention in Las Vegas turns serious when the costumed villain Angle Man is found dead. Who killed him and why? Five famed detectives and one policewoman — Jonni Thunder, Jonny Double, Harvey Bullock, Christopher Chance, Angel O’Day, and Liza Warner — are about to find out. Guest starring Earth-Four’s Michael Mauser. This Crisis crossover is inspired by a scene in Crisis on Infinite Earths #11!
