"Henri Dubois! In the name of the King of England I arrest you for the murder of——"

The detective's words were stopped by a blow.

A wild struggle promptly ensued. The man turned on him like a tiger, and the Turks joined in. Gros Jean, too, ran back to take a hand in the fray. Fairholme, Sir Hubert, Daubeney and Talbot flung themselves on the would-be rescuers, and the four French sailors of the Belles Sœurs leaped ashore to assist their passenger in this unlooked-for attack.

Frantic yells and oaths came from the confused mob, and knives were drawn. Talbot had but one desire in life—to get his fingers on Dubois' throat. He had almost reached him, for Winter clung to his prey with bull-dog tenacity, when an astounding thing happened. The Frenchman's handsome moustaches fell off, and beneath the clever make-up on her face were visible the boldly handsome features of La Belle Chasseuse, now distorted by rage and fear.

"You fool!" yelled Talbot to Winter. "You have let him escape!"

Tearing himself from the midst of the fight, he was just in time to see the female figure, which he now knew must be Dubois masquerading in his mistress's clothes, jumping into a cab and driving off towards the Corso Vittorio Emmanuele.

"Come on, Fairholme!" he cried. "He cannot get away! Here comes an empty carriage!"

But now Macpherson and his allies had reached the scene. Using a "monkey-wrench or the first thing to hand," they placed the Turks, Gros Jean, and the crew of the Belles Sœurs on the casualty list.

Mr. Winter's indignation on finding that he had arrested a woman was painful. In his astonishment he released his grasp and turned to look at the disappearing vehicle containing the criminal he so ardently longed to lay hands upon.
