In this early serial killer novel, Ellery Queen stalks a mass murderer through the streets of 1940s New York.

In the dog days of August, it is no surprise to see New Yorkers perspire. But this summer, a killer called the Cat gives the city a new reason to sweat. He selects his victims seemingly at random and strangles them, then escapes without leaving a clue. As the death toll climbs and the press whips the public into a horrified frenzy, Gotham teeters on the edge of anarchy.

Ellery Queen, the brilliant amateur sleuth, has gone into retirement when the Cat begins to kill. As his father, a seasoned homicide detective, leads the investigation into the murders, Ellery tries to avoid getting involved. When Queen discovers a clue that could hold the secret to untangling the puzzling crimes, he pounces on the opportunity to crack the case. But unfortunately for him—and for the citizens of 1940s New York City—he’s barely scratched the surface...

Combining gobsmacking deduction with plenty of period detail, Cat of Many Tails is among the most beloved of Ellery Queen’s timeless mystery novels. Reissued for the first time in nearly half a century, the book retains a place in popular culture as one of the first serial killer novels ever written; and, to this day, it’s still one of the best.
