"I haf long suspected," he said, "that Hendrik Martinus iss a spy in the service of France, a traitor for his own profit, because he loves nothing but himself und his. He has had remarkable prosperity of late, a prosperity for which no one can account, because he has had no increase of business. Believing that a Frenchman wass here, a spy who wished to communicate with him, I set Peter to watch his house, und the result you know."

"Then it is for us to go there and seize this spy," said Robert.

"It iss what I wish," said Mynheer Huysman, "und we may trap a traitor und a spy at the same time. It is well to haf money if you haf it honestly, but Hendrik Martinus loves money too well."

He took from a drawer a great double-barreled horse pistol, put it under his coat, and the four, quietly leaving the house, went toward that of Hendrik Martinus. There was no light except that of the moon and, in the distance, they saw a watchman carrying a lantern and thumping upon the stones with a stout staff.

"It iss Andrius Tefft," said Mynheer Jacobus. "He hass a strong arm und a head with but little in it. It would be best that he know nothing of this, or he would surely muddle it."

They drew back behind some shrubbery, and Andrius Tefft, night watchman, passed by without a suspicion that one of Albany's most respected citizens was hiding from him. The light of his lantern faded in the distance, and the four proceeded rapidly towards the house of Hendrik Martinus, entering its grounds without hesitation and spreading in a circle about it. Robert, who lurked behind a small clipped pine in the rear saw a door open, and a figure slip quietly out. It was that of a man of medium height, and as he could see by the moonlight, of dark complexion. He had no doubt that it was a Frenchman, the fellow whom Peter had seen enter the house.

Robert acted with great promptness, running forward and crying to the fugitive to halt. The man, quick as a flash, drew a pistol and fired directly at him. The lad felt the bullet graze his scalp, and, for a moment, he thought he had been struck mortally. He staggered, but recovered himself, and raising his own pistol, fired at the flying figure which was now well beyond him. He saw the man halt a moment, and quiver, but in an instant he ran on again faster than ever, and disappeared in an alley. A little later a swift form followed in pursuit and Robert saw that it was Tayoga.

Young Lennox knew that it was useless for him to follow, as he felt a little dizzy and he was not yet sure of himself. He put his hand to his hair, where the bullet had struck, and, taking it away, looked anxiously at it. There was no blood upon either palm or finger, and then he realized, with great thankfulness, that he was merely suffering a brief weakness from the concussion caused by a heavy bullet passing so close to his skull. He heard a hasty footstep, and Mynheer Huysman, breathing heavily and anxious, stood before him. Other and lighter footsteps indicated that Peter also was coming to his aid.

"Haf you been shot?" exclaimed Mynheer Jacobus

"No, only shot at," replied Robert, whimsically, "though I don't believe the marksman could come so close to me again without finishing me. I think it was Peter's spy because I saw him come out of the house, and cried to him to halt, but he fired first. My own bullet, I'm sure, touched him, and Tayoga is in pursuit, though the fugitive has a long lead."
