"Can he be watching me? Can he know what I am here for?" thought Gerard. "Impossible."

He went briskly off, walked along a street or two, made a detour, and came back.

The man had vanished. But, lo! on Gerard looking all round, to make sure, there he was a few yards behind, apparently fastening his shoe.

Gerard saw he was watched, and at this moment observed in the moonlight a steel gauntlet in his sentinel's hand.

Then he knew it was an assassin.

Strange to say, it never occurred to him that his was the life aimed at. To be sure he was not aware he had an enemy in the world.

He turned and walked up to the bravo. "My good friend," said he, eagerly, "sell me thine arm! a single stroke! See, here is all I have:" and he forced his money into the bravo's hands. "Oh, prithee! prithee! do one good deed, and rid me of my hateful life!" and even while speaking he undid his doublet, and bared his bosom.

The man stared in his face.

"Why do ye hesitate?" shrieked Gerard. "Have ye no bowels? Is it so much pains to lift your arm and fall it? Is it because I am poor, and can't give ye gold? Useless wretch, canst only strike a man behind; not look one in the face. There, then, do but turn thy head and hold thy tongue!"

And with a snarl of contempt he ran from him, and flung himself into the water.
