His first impulse was to go upstairs and call the police, in the person of Detective Inspector Evelyn Throckmorton, but then he had second thoughts. How could he explain his own presence in the house? If he tried, he’d have to explain everything he’d done since he’d arrived in the United Kingdom, including the identity of his client. Also, his client had not asked him to search this house; he’d done it on his own. He would make a terrible witness, too, having seen nothing and having heard only footsteps and gunshots.

Discretion, in this case, was definitely the better part of valor. He stepped over a body, back into the office, and wiped anything he might have touched. Then he closed the office door, wiped the knob, and secured the two wine racks in place. He wiped the knob of the wine cellar door and went upstairs, wiping anything else he might have touched in the house. Finally, he put on his raincoat, retrieved his umbrella from the stand, opened the door a crack, and peered up and down the mews. It was dark now, and streetlights were on, but the mews was empty. He let himself out, wiped the doorknob, inside and out, closed the door behind him, and walked down Farm Street in the direction of Berkeley Square.

He had reached the square before he saw anyone else, and he kept the umbrella low to keep anyone from remembering his face. Deciding against a taxi, he walked across Berkeley Square and up the little hill into Dover Street. The gallery was closed and dark. He dropped the keys to the Farm Street house through the mail slot.

What now? He wanted to talk to Lance. He walked up to New Bond Street, then to Conduit Street, found a cab at the Westbury Hotel, and gave the driver the Chester Street address that he’d heard Sarah give Lance. As the cab made its way through the West End, he thought about the two dead men on the wine cellar floor at Lance’s house. How long would it be before anyone found them? Lance clearly didn’t intend to go back to the house anytime soon. Was there a housekeeper or a cleaning lady? If so, would she go down to the wine cellar? He retraced his own steps, thought about the time line from a policeman’s perspective. He was without an alibi from the time he left the gallery until he got into the taxi at the Westbury. How long was that? An hour at the most. Where else could he have been for an hour? Monica and Sarah knew he had the keys to the house, including the wine cellar. But no one would have any reason to question them, would they?
