"Robbed!" he said. "No watch there, anyway, and nothing where you'd expect to find his purse. Robbery and murder—murder for the sake of robbery—that's what it is, Mr. Viner! Westbourne Grove way, you say this fellow went? And five minutes' start!"
"Is it any good getting a doctor?" asked Viner.
"A thousand doctors'll do him no good," replied the policeman grimly. "But—there's Dr. Cortelyon somewhere about here—number seven in the terrace. One of these back doors is his. We might call him."
He turned the light of his lantern on the line of doors in the right-hand wall, and finding the number he wanted, pulled the bell. As its tinkle sounded somewhere up the yard behind, he thrust his whistle into Viner's hand.
"Mr. Viner," he said, "go up to the end of the passage and blow on that as loud as you can, three times. I'll stand by here till you come back. If you don't hear or see any of our people coming from either direction, blow again."
Viner heard steps coming down the yard behind the door as he walked away. And he heard more steps, hurrying steps, as he reached the end of the passage. He turned it to find an inspector and a sergeant approaching from one part of the terrace, a constable from another.
"You're wanted down here," said Viner as they all converged on him. "There's been murder! One of your men's there—he gave me this whistle to summon further help. This way!"
The police followed him in silence down the passage. Another figure had come on the scene. Bending over the body and closely scrutinizing it in the light of the policeman's lantern was a man whom Viner knew well enough by sight—a tall, handsome man, whose olive-tinted complexion, large lustrous eyes and Vandyke beard gave him the appearance of a foreigner. Yet though he had often seen him, Viner did not know his name; the police-inspector, however, evidently knew it well enough.
"What is it, Dr. Cortelyon?" he asked as he pushed himself to the front.
"Is the man dead?"
Dr. Cortelyon drew himself up from his stooping position to his full height—a striking figure in his dress jacket and immaculate linen. He glanced round at the expectant faces.
