With crooks to cuff and pimps to put behind bars, detectives Carella and Meyer of the 87th Precinct simply don’t have the time or patience to deal with a prank caller—even if he has phoned murder threats to two dozen local shop owners. What they fail to realize, however, is they aren’t dealing with a heckler who’s ringing round for kicks but rather a modern-day Moriarty known only as the Deaf Man—and these phone calls are just his first move in a calculated scheme to pull off the bank robbery of the decade. Further calls darken a lovely spring with suspicion and fear, before a brutal murder whips things into a frenzy, prompting Carella and Meyer to scour the town for clues to the Deaf Man’s identity. As the detectives grasp at a few tenuous threads of the larger plot, those targeted by the calls clamor for the cops to slam the case closed before more of them wind up stiffs.
