introduced himself as Calvi, and agreed to confirm the bookings in writing at once. He also booked a return air ticket from Paris to Valencia, arriving on the evening for which he had made the hotel reservation, and returning to Paris the following evening.
While the telephone call to Valencia was coming through he had already written his letter of confirmation to the hotel. It was short and to the point. It confirmed the two bookings and added that as the signatory, M. Calvi, would be travelling constantly until his arrival in Valencia, he had ordered a book on the history of Spain to be sent forward to him, care of the Hotel Metropol, from Paris, and asked the hotel to be kind enough to hold it until his arrival.
Calvi estimated that if the book were intercepted and opened the moment he inquired for it under his reed name the expression on the clerk's face would indicate there was something wrong and give him time to get away. Even if he were caught, he could claim to be an innocent party doing a favour for a friend and with no suspicion of any ulterior motive in the absent Calvi's request.
With the letter signed left-handed in the name of Calvi, sealed and stamped for posting, he went to work on the book he had bought that afternoon. It was indeed a history of Spain, expensive and heavy, on fine quality paper, with plenty of photographs which gave it added weight.
He bent back the two covers and held them together with an elastic band. The intervening 400 pages he secured as a block to the edge of the kitchen table with two carpenter's clamps.
Onto his block of paper he began to work with the thin, razor-sharp scalpel acquired the same afternoon. He sliced away for almost an hour until a square, set 1 Vi inches into the area of the page from each edge, had been cut out, forming a box 7 inches by 6 inches and 3 inches deep. The insides of this hollow square he daubed thickly with a tacky glue, and smoked two cigarettes while waiting for the glue to dry. When it was hard the 400 pages would never open again.
A cushion of foam rubber, cut to size, went into the hollow to replace the IV2 pounds of paper which had been cut out and which he had weighed on the kitchen scales. He dismantled the slim Browning 9-mm automatic he had acquired on a trip into Belgium two months earlier when he had used and thrown into the Albert Canal his previous gun, a Colt .38. He was a careful man, and never used the same shooter twice. The Browning had had the tip of its barrel exposed to half an inch, and the barrel's end tooled to take a silencer.
A silencer on an automatic is never truly quiet, despite the efforts of the sound-effects men in television thrillers to pretend it is. Automatics, unlike revolvers, do not have a closed breech. As the bullet leaves the barrel the automatic's jacket is forced backwards to expel the spent cartridge and inject a fresh one. That is why they are called automatics. But in that split second as the breech opens to expel the used shell, half the noise of the explosion comes out through the open breech, making a silencer on the end of the barrel only 50 per cent effective. Calvi would have preferred a revolver with its breech closed during firing, but he needed a flat gun to go into the cavity in the book.
The silencer he laid beside the parts of the Browning was the largest component, 6 Vi inches long. As a professional he knew the champagne-cork-sized silencers shown on television are as much use as a hand-held fire extinguisher to put out Mount Vesuvius.
Arranged side by side on top of the rubber cushion, the five parts, including silencer and magazine, would not quite fit, so he smacked the magazine into the automatic's handle to save space. He marked out the beds of the four components with a felt-nib pen and began to cut into the foam rubber with a fresh scalpel. By midnight the parts of the gun lay peacefully in their foam beds, the long silencer vertical, parallel to the book's spine, the barrel,
