"She's playing a pretty dangerous part, is our famous Mademoiselle Little Person," he said. "If they got on to the fact that she's working with us, I suppose it would go hard with her."

"The Lord have mercy on her if Miridoff ever suspects what she's doing!" said Varden gravely. "From now on she's going to be doubly valuable to us. You see, it's going to be necessary to watch them closely to forestall any attempts on the life of the prince. And we'll have to depend on Anna Petrowa for that. I don't know which of them is likely to stand in the most danger from now on, Prince Peter or our little dancer."

At this point the rest of the party returned from the inner room and an immediate move toward the street was made.

"There are two cars waiting in the next street for us," whispered Varden, as they cautiously descended the creaky stairs. "I am to accompany the prince home—sort of bodyguard, you know. Will you perform like service for Mademoiselle Petrowa?"

They stepped out into the street to find that the darkness of night had given place to the light of early dawn. It was decidedly chilly. Fenton wrapped himself snugly in his cloak and dropped back beside the diminutive, muffled figure of the dancer.

At that instant a startled shout from ahead broke the stillness. Fenton saw a figure suddenly loom up out of the darkness with arm upraised. Something flashed bright in the hand of the unknown assailant as he hurled himself directly at Prince Peter.

Fenton could see that the man with gleaming dagger raised to strike the blow that would throw the control of Ironian destinies into the hands of the King's party was not alone. Another ruffian had emerged from the shadows of a deep court and was struggling with Varden. He could see that the prince, taken off his guard, had recoiled a step and was endeavouring to draw his sword, around which his cloak had become wrapped in a sudden flurry of the wind. All this the Canadian took in during the fraction of a second following the warning shout from in front. Instantly he stripped off his cloak and plunged ahead, throwing a word of warning back over his shoulder to his companion.

Fenton had been a star half-back in his college days. He covered the intervening space in faster time than he had ever done when the touch-line was ahead and the opposing wing men thundered after. The sound of his flying feet caused the assailant to pause and glance in that direction, which probably saved the prince's life, for before the dagger could descend Fenton's fist had found the fellow's jaw with a glancing blow. The blow was partly spent when it landed, but it had enough force left behind it to spin the assassin around to one side. The next moment Fenton's left hand shot forward and gripped the dagger arm.

The assassin was a wiry fellow, built on the lines most commonly seen in the Near East. He had short, bowed legs, powerful shoulders, arms of almost gorilla-like length. His large, hairy hands had an almost Simian strength, as Fenton found in the struggle that ensued. The fellow fought with the fury of a wild beast, writhing and snarling and struggling to reach Fenton's throat with his free hand. It was all Fenton could do to ward off that powerful paw which would choke the life out of him once it had found its grip. At the same time, it required all the strength he could summon to hold back his opponent's right hand, which still grasped the dagger.

They swayed back and forth, each straining for an advantage. It was a long time before the assassin relaxed his strenuous efforts for a winning hold. Finally, however, Fenton's chance came. His opponent stopped for a moment for breath, and his left hand dropped. Instantly Fenton stepped back and planted a short-arm upper cut in the general direction of his face. It landed fairly on the point of the chin. The ruffian crumpled up at the knees and dropped back on the ground with a thud. The knife, slipping from his fingers, clattered on the pavement at Fenton's feet.
