The one thing supremely important to the young spy was that he should not be seen. And he doubted whether it were now possible even to retreat, without making some slight noise to put those mysterious others upon the alert. They had almost walked into an ambush. His brain ached with the wonder. Who could they possibly be? What conceivable object, save to stop Felix Vanston's tarantasse, could lead men to hide in the wood at that hour? And he could not think of any others besides himself who would be likely to wish to do that. He was horribly agitated. For these men, no doubt, were as desirous as himself of being unobserved. They made no noise. In the intense silence of the forest he could not hear a sound. And he dared not make one.

Nothing was less desired by this young man than any kind of a fight. He wanted a murder, that was all. One accomplice to hold the horse, one to hold the coachman—and himself to knife Felix, who would almost certainly be unarmed. This sudden, wholly unexpected check upset his nerves. His subordinates looked to him for orders. He had none to give. But a few minutes' reflection steadied his nerves. They must somehow retreat, unobserved. They must cross the road lower down, and re-enter the wood on the other side of the road. Then they must rapidly work their way along, to a point between the village and the spot where the ambush lay, and there await the coming of their victim.

With inconceivable precaution they crept away. Among pine trees there is little undergrowth, few dead twigs to crack beneath the foot. Nevertheless, in that silence, for three men to retreat unheard was something of a feat; and Streloff, when after a quarter of an hour that seemed an eternity they stood out of sight and earshot, at the edge of the road, felt that he was proving himself a born spy.

They listened. Not a sound broke the calm of the summer night except the sigh of the wandering breeze in the tops of the pines. Like three flitting shadows, they crossed the road; and entered the wood upon the farther side. Streloff was immensely anxious to go on for at least half a mile—to meet the tarantasse at as great a distance as possible from where the ambush waited. But he was bothered, for the unknown others had chosen the very place he had decided to occupy—in the deep part of the wood, yet far enough from the village to prevent sounds from being heard. Who could they be? As they pushed along, he told himself that he was a fool. Doubtless these men were but three or four tramps, perhaps on their way from the harvest of one village to that of another—sleeping in the woods on their journey. But, whoever they were, they must not be witnesses of what was to take place.

And then, before he and his followers had reached a spot parallel to that where they had seen the lighted match, they heard the ringing of the harness-bells upon Felix's carriage.

For a moment they paused, simultaneously, while the musical ting, ting, ting, sounded each second clearer. This sudden destruction of his plans caused Streloff to hesitate—to hesitate three or four long, endless seconds, before he said: "Run back—back—as far down the road as we can."

They ran. But behind them the bells of the tarantasse rang more and more piercing sweet. And then there was a long, wild shout, and Streloff faced suddenly round, to see that a man had sprung from the other side of the road and caught the horse's head, and that Felix Vanston was standing up in the tarantasse, and had just hurled a second man down upon the ground; while two or three others were winding ropes about the prostrate form of Max, whom they had dragged from his seat.

Streloff gave no orders to his followers. He forgot all about them. Without a second thought he sprang into the mêlée. He never doubted that these men, though unknown to him, were his allies, for manifestly they were hostile to Felix; and he ran forward, his knife bare, shouting wildly, "Kill him—kill him! What is the use of taking him prisoner?"

He had brought no revolver, for he had meant to do his work silently, and shots carry on a still night. But his sudden appearance from nowhere seemed to strike the other men for a breathing space still with amazement. He saw then that they were masked.

"Help! Help!" cried Felix, writhing in the grip of three of them.
