Rosal blandly admitted he had carried the oils with him in a wooden box. “I brought them over from Vichy for a friend,” he said, “and delivered them to his brother at the Waldorf-Astoria. I was assured the duty had been paid and I never dreamed, of course, there was anything irregular.”

As for the diamonds, Rosal admitted he had approached a dealer and offered to sell him several diamonds. But he insisted that when no agreement was reached, he had taken the gems on to Venezuela, where he had disposed of them. Had he made the sale in New York, he added with a shrug, he would naturally have paid the required customs duty.

There was nothing further that Customs could do about the matter and the case was closed. The report was filed away to gather dust until Rosal’s name was linked with that of Tarditi.

On September 30, six weeks after Cozzi had found the old report, the Sûreté advised the Narcotics Bureau that Rosal and Tarditi had purchased tickets for a flight to New York and it was suspected they would be carrying narcotics. Tarditi was booked to arrive at Idlewild International Airport on October 1, and Rosal was due to arrive a day later. Bourbonnais was scheduled to leave Paris a short time after Tarditi as the steward aboard TWA’s Flight 801.

As the original tip on the case had come to the Narcotics Bureau, the investigation was in the hands of District Director George H. Gaffney, a veteran agent, with Customs playing a supporting role.

Thus began one of the most remarkable cases of Federal agency cooperation in the war against smuggling. Gaffney laid his plans well, and when TWA’s Flight 801 touched down at Idlewild at 5 P.M. on October 1, a squad of Narcotics and Customs agents was waiting to place Tarditi under surveillance. Customs inspectors had been alerted to signal an identification when Tarditi handed over his baggage declaration, and to make only a cursory examination of a single piece of his luggage.

Tarditi stepped from the plane wearing a trench coat and a pork-pie hat set jauntily at an angle. He seemed unconcerned when the inspector asked him to open the single bag he carried to the inspection station. The inspector noted on his declaration that his destination was the Sherry Netherlands Hotel.

And so it was that Tarditi passed through Customs with no hint given that several pairs of eyes were watching every move he made. A porter carried Tarditi’s luggage to a waiting taxi while a radio message was flashed from Idlewild to a squad of agents in midtown Manhattan that the suspect was enroute to the Sherry Netherlands. Agents were instructed to keep him under surveillance when he reached the hotel.

The taxi driver stowed Tarditi’s bag into the trunk of his cab and slid behind the wheel. He said, “Where to, sir?”

Tarditi replied, “To the Savoy Hilton.”
