"I hope we didn't muff it, Captain, but I can't see anything here," said Parkhurst. Roal stared along the length of Transite Street. There was no Starhouse with the garish crimson sign he remembered. But the old abandoned warehouse was still where it had always been--where he would have sworn Starhouse should have been. Roal began to question his own sanity. Surely he could not be so wrong about it as this indicated. He knew he had received the phone call, but he couldn't be too sure it was Alayna's voice because the narrow circuits stripped away most of the golden overtones that made her voice a sound of such exquisite beauty. Or someone might be playing a colossal joke on him. He didn't know--except he knew that somehow he had failed. He circled the block, directing the deputies to cover adjacent squares. When they finally met again in front of the old warehouse full blackness had settled over Heliopolis and all the blaze of its million lights boiled skyward into the blackness of space. "It must have been a bum steer," said Roal, "There's nothing more that we can do tonight. I'll check up on my information and let you know." "O.K., Captain," said Parkhurst dubiously. His manner made it evident that they wondered if Roal were off the track a bit. He had never appeared so fumblingly on an investigation before. When they were gone, Roal circled the block once again and then walked up and down the length of Transite amid the glare of the signs and the roaring bedlam of the street of crime. There was simply no Starhouse. It was maddening to know he had followed this very path right to its door. He knew it was no illusion or drug-inspired dream. But it did not lead to Starhouse now. Alayna was in deadly danger, and he knew of no way to find her or help her. He was about to turn about and return to his office for a futile check on the progress being made by the Identification Office, when a thought formed in his mind. There was yet one clue that he had not exploited--a clue that stuck out so close to his face that he hadn't seen it. The Martians--the Martians who had stolen the pellet of _harmeena_ from him on the desert. They were in contact with the dope peddlers of Starhouse. He raced to the nearest televise booth and called Commander Calvin's home. But as the signal rang at the other end of the line Roal slowly replaced the receiver. He knew what Calvin's reaction would be. A hundred years of strict peace with the Martians could not be violated by forceful entry into one of the burrows. Calvin would never consent to that, especially since he believed that the whole mystery was only a pipe dream in Roal's mind anyway. Roal abandoned the call and placed another one. In a moment he got an answer. "Hello, Shorty," he said. "Do you feel like a job tonight?" "Sure, if it's a shooting job. I haven't had any excitement for a long time." "I'm serious, Shorty, and it may turn out to be a shooting job. Bring along your lance."
