“I need your help,” he slurred, looking up at Sloane, who just stood there, watching him carefully.

Cedric stumbled, took a pace backward, and fell heavily on the floor, gasping for breath. Sloane walked slowly around the desk, his eyes never leaving the chairman as he lay on the floor fighting for his life. He picked up the bottle and unscrewed the cap. Cedric stared up at him as he shook the pills on to the floor, just out of his reach. He then wiped the empty bottle with a handkerchief from his top pocket and placed it in the chairman’s hand.

Sloane leaned over and listened carefully, to find that the chairman was no longer breathing quite so heavily. Cedric tried to raise his head, but he could only watch helplessly as Sloane gathered up all the papers on his desk that he’d been working on for the past twenty-four hours. Sloane turned and walked slowly away, without once looking back, avoiding those eyes that were burning into him.

He opened the door and looked out into the corridor. No one in sight. He closed the door quietly behind him and went in search of the chairman’s secretary. Her hat and coat were no longer on the stand, so he assumed she must have left for the weekend. He tried to remain calm as he walked down the corridor, but beads of sweat were pouring off his forehead and he could feel his heart pounding.

He stood for a moment and listened, like a bloodhound sniffing for danger. He decided to throw the dice once again.

“Anyone around?” he shouted.

His voice echoed through the high-ceilinged corridor as if it were a concert hall, but there was no response. He checked the executive offices one by one, but they were all locked. No one on the top floor, other than Cedric, would still be in the office at six o’clock on a Friday evening. Sloane knew there would still be junior staff in the building who wouldn’t think of leaving before their bosses, but none of them would consider disturbing the chairman, and the cleaners wouldn’t be returning until five o’clock on Monday morning. That only left Stanley, the night porter, who would never budge from his comfortable chair at the front desk unless the building was on fire.

Sloane took the lift to the ground floor and, as he crossed the lobby, he noticed that Stanley was dozing quietly. He didn’t disturb him.

“The Rijksmuseum,” said Sam as they entered the Dutch national gallery, “houses one of the finest collections on earth. The Rembrandts are showstoppers but the Vermeers, De Wittes, and Steens are also among the finest examples of the Dutch masters you’ll ever see.”
