The gang deliver the dagger to Joseph (Joe Dassin), proprietor of the traveling fair display, who will smuggle it out of the country. The gang members then go to police headquarters to "reveal" their discovery of weapons in the car. The inspector asks Simpson to vouch for Harper and Lipp's whereabouts that day. Simpson, seeming to waver, throws in his lot with the others, and backs up their alibi. Before the police release Simpson and the others, the trapped bird in the Topkapı triggers the alarm, alerting police officers across Istanbul. When word of the Topkapı alarm reaches the police, Major Tufan confronts the thieves, displaying Simpson's last note, which has just enough information to link all of them to the theft. Tufan tells them all that he now knows why they were in Turkey. "A little bird told me," he says.
