The hawk-faced man looked up with a scowl and said something just as the portly Nicholas and a waiter appeared in the background, as if passing casually by.

The thick-set man bent down till his face was close to Helzephron's. He said something also, with an unpleasant smile.

Instantly Helzephron leapt up and drove his fist full into the other's face.

The fight that followed ended very speedily. The thick-set man took the blow calmly. Then, without heat, and in a fashion which instantly told me the truth of the matter, he set about Helzephron, hitting him where and when he chose, until a shouting crowd of guests and waiters separated the combatants and a policeman and commissionaire hurried them away from the gallery.

During all the tumult Mr. Danjuro sat quietly smoking a cigarette.

"That was Mr. Wag Ashton, the pugilist," he remarked. "Honourable Nicholas and the waiter saw that the honourable Helzephron struck him first. I think the Major will be resting for a day or two before Mr. Ashton summonses him for assault."

I felt faint with surprise and amazement.

"So you, you arranged ..."

He interrupted me. "Now let us finish our dinner in peace," he said. "Some river trout, meunier, are coming."
