Rafferty grabbed the bag and threw it on the backseat of the taxi. He’d decided to make Martinez’s death somewhat more protracted than originally planned. After all, he had nothing else to do for the next hour.

He waved the gun in the direction of a wooden chair that had been placed directly below the lightbulb. It was already splattered with dried blood from previous executions. He pushed his victim down with considerable force, and before Don Pedro had a chance to react, he had tied his arms behind his back, but then he’d carried out this particular exercise several times before. Finally he tied Martinez’s legs together, then stood back to admire his handiwork.

All Rafferty had to decide now was how long the victim would be allowed to live. His only constraint being, he had to be at Heathrow in time to catch the early morning flight to Belfast. He checked his watch. He always enjoyed seeing that look on the victim’s face when they believed there still might be a chance of survival.

He returned to the taxi, unzipped Martinez’s bag, and counted the bundles of crisp five-pound notes. At least he’d told the truth about that, even if he was more than £226,000 short. He zipped the bag back up and locked it in the boot. After all, Martinez would no longer have any use for it.

The area commander’s orders were clear: once the job had been completed he was to leave the body in the warehouse and another operative would deal with its disposal. The only thing required of Rafferty was to make a phone call and deliver the message, “Package ready for collection.” After that, he was to drive to the airport and leave the taxi, and the money, on the top level of the long-term car park. Another operative would be responsible for collecting it and distributing the cash.

Rafferty returned to Don Pedro, whose eyes had never left him. If the chauffeur had been given the choice, he would have shot him in the stomach, then waited a few minutes until the screaming died down, before firing a second bullet into his groin. More screaming, probably louder, until he finally forced the gun into his mouth. He would stare into his victim’s eyes for several seconds and then, without warning, pull the trigger. But that would have meant three shots. One might go unnoticed, but three would undoubtedly attract attention in the middle of the night. So he would obey the area commander’s orders. One shot, and no screaming.

The chauffeur smiled at Don Pedro, who looked up hopefully, until he saw the gun heading toward his mouth.

“Open up,” said Rafferty, like a friendly dentist coaxing a reluctant child. One common factor among all his victims was the chattering teeth.

Martinez resisted, and swallowed one of his front teeth in the unequal struggle. Sweat began to pour down the fleshy folds of skin on his face. He was only made to wait a few more seconds before the trigger was pulled, but all he heard was the click of the hammer.
