“He is in Frankfort to-night, and said he entered by the western gate just before it was closed.” “Then he is a liar,” commented Gottlieb, with his usual bluntness. “Such I strongly suspect him to be. Nevertheless, here he is, and the question I wish answered is, how did he get in?” “He must have come over the wall, which can hardly be prevented if an incomer has a friend who will throw him a rope.” “It may be prevented if the walls are efficiently patrolled. See instantly to that, Gottlieb, and set none but our own woodlanders on watch.” Several days passed, and Wilhelm kept a sharp lookout for von Brent, or any other of the Archbishop’s men, but he saw none such, nor could he learn that the lieutenant had left the city. He came almost to believe that the officer had spoken the truth, when distrust again assailed him on finding in the barracks a second document almost identical with the first, except that it contained the words, “Second warning,” and the dirk had been driven half its length into the lid of the desk. At first he thought it was the same parchment and dagger, but the different wording showed him that at least the former was not the same. He called Gottlieb, and demanded to know who had been allowed to pass the guards and enter that room. The honest warrior was dismayed to find such a thing could have happened, and although he was unable to read the lettering, he turned the missive over and over in his hand as if he expected close scrutiny to unravel the skein. He then departed and questioned the guards closely, but was assured that no one had entered except the Commander. “I cannot fathom it,” he said on returning to his master, “and, to tell truth, I wish we were well back in the forest again, for I like not this mysterious city and its ways. We have kept this town as close sealed as a wine butt, yet I dare swear that I have caught glimpses of the Archbishop’s men, flitting here and there like bats as soon as darkness gathers. I have tried to catch one or two of them to make sure, but I seem to have lost all speed of foot on these slippery stones, and those I follow disappear as if the earth swallowed them.” “Have you seen von Brent since I spoke to you about him?” “I thought so, Master Wilhelm, but I am like a man dazed in the mazes of an evil dream, who can be certain of nothing. I am afraid of no man who will stand boldly up to me, sword in hand, with a fair light on both of us, but this chasing of shadows with nothing for a pike to pierce makes a coward of me.”
