At one moment Guest's horrified face was before him, and in a puzzled way he felt that his friend had left him with the idea that he had slain Brettison, and that he ought to have made that portion of his trouble clear to him; but at that time it was as if he were fettered by the horrors of a nightmare-like dream. But he waved these thoughts aside. They were as nothing to the terrible perplexity he had to master, and the first step toward that mastery was to find Brettison, whom he had last seen on the morning appointed for the wedding, wishing him happiness and every good thing which could fall to a bridegroom's lot. And now? What did it all mean? How could he clear up the chaos which bade fair to wreck his brain. Brettison could not have returned; and yet how strange it all was! What could he do? One thing shone out, however, clearly; and that was the knowledge that he could come back here and stay without being haunted by the presence of a great horror close at hand. He even began to grasp the fact that, for a long time past, he had been needlessly shunning his rooms and living away in a morbid state, always dreading discovery; and opening his doors at every visit, fully expecting to find himself face to face with the police, waiting to trap him in his lair. How he had suffered! How he had stolen to his chambers at night, creeping up to his door furtively, and, after entering, examining the closet, and making sure that it had not been tampered with and opened in his absence. It had been a terrible period of agony, such as had turned him old before his time; and now he had discovered that his suffering and dread had been vain and empty; that he had stayed away from the inn for naught, unless all this was imagination; another of the horrible nightmare dreams by which he had been haunted ever since that dreadful day. At last he grew calmer, and felt able to look matters in the face. The great horror had passed away, and in so passing it had roused him to action. There was work to do, a strange complication to solve; and he settled in his own mind how that was to be done. He must find Brettison at once; and the great question was: Where could he be? Here was a grand difficulty at once. Where would a man like Brettison be likely to sojourn?--a man who ranged through the length and breadth of the country in pursuit of his specimens. In an ordinary way. But what would he be doing now and what had he done? Stratton shuddered, and pictured a strange scene, one upon which he dare not dwell; and, leaping up, he took matches and a candle with the intention of going to his friend's room to try and pick up the clue there; but by the time he reached his door he was face to face with the first obstacle. Brettison's door was locked again, and, without re-summoning the help they had had that evening, entrance was impossible.
