He had only crossed the little street that runs beside the restaurant and passed into the shadow of the National Gallery when, at the base of the Irving Memorial, from each side he was fiercely attacked. A young man of eminently respectable appearance kicked his legs from under him, and another of equally impeccable exterior made an honest effort to knock off his head.

Sam plunged heavily to the sidewalk. As he sprawled forward his hat fell under him and in his struggle to rise was hidden by the skirts of his greatcoat. That, also, he had fallen heavily upon his hat with both knees Sam did not know. The strange actions of his assailants enlightened him. To his surprise, instead of continuing their assault or attempting a raid upon his pockets, he found them engaged solely in tugging at the hat. And so preoccupied were they in this that, though still on his knees, Sam was able to land some lusty blows before a rush of feet caused the young men to leap to their own and, pursued by several burly forms, disappear in the heart of the traffic.

Sam rose and stood unsteadily. He found himself surrounded by all of those who but a moment before he had left contentedly dining at Pavoni's. In an excited circle waiters and patrons of the restaurant, both men and women, stood in the falling snow, bareheaded, coatless, and cloakless, staring at him. Forsythe pushed them aside and took Sam by the arm.

"What happened?" demanded Sam.

"You ought to know," protested Forsythe. "You started it! The moment you left the restaurant two men grabbed their hats and jumped after you; a dozen other men, without waiting for hats, jumped after them. The rest of us got out just as the two men and the detectives dived into the traffic."

A big man, with an air of authority, drew Sam to one side.

"Did they take anything from you, sir?" he asked.

"I've nothing they could take," said Sam. "And they didn't try to find out. They just knocked me down."

Forsythe turned to the big man.

"This gentleman is a friend of mine, inspector," he said. "He is a stranger in town and was at Pavoni's only by accident."
