who he is?" "Never saw him before." For perhaps two minutes Gregory continued to stare. Then he moved over to the side of the house and braced against the wall continued his close and anxious inspection. After a time he turned away and, passing behind the boxes, made his way into the wings. Bassett's curiosity was aroused, especially when, shortly after, Gregory reappeared, bringing with him a small man in an untidy suit who was probably, Bassett surmised, the stage manager. He saw the small man stare, nod, stand watching, and finally disappear, and Gregory resume his former position and attitude against the side wall. Throughout the last act Gregory did not once look at the stage. He continued his steady, unwavering study of the man in the sixth row seat next the aisle, and Bassett continued his study of the little man. His long training made him quick to scent a story. He was not sure, of course, but the situation appeared to him at least suggestive. With the end of the play he wandered out with the crowd, edging his way close to the man and girl who had focused Gregory's attention, and following them into the street. He saw only a tall man with a certain quiet distinction of bearing, and a young and pretty girl, still flushed and excited, who went up the street a short distance and got into a small and shabby car. Bassett noted, carefully, the license number of the car. Then, still curious and extremely interested, he walked briskly around to the stage entrance, nodded to the doorkeeper, and went in. Gregory was not in sight, but the stage manager was there, directing the striking of the last set. "I'm waiting for Gregory," Bassett said. "Hasn't fainted, has he?" "What d'you mean, fainted?" inquired the stage manager, with a touch of hostility. "I was with him when he thought he recognized somebody. You know who. You can tell him I got his automobile number." The stage manager's hostility faded, and he fell into the trap. "You know about it, then?"
