After I had learned this, I put in a visicall to the Oak Drive mansion. The butler's face appeared on the screen. I was too late. I got hold of Harry as quick as I could, but I could see right away that he had already found out. Mrs. Campbell had taken Sukey Jones and left last night for Venus. I had known Harry Thurbley for ten years, and he was a phlegmatic sort. He had the kind of unshakable calm and nerve you only find in a man that's made peace with death a couple of times or so out beyond the planets. Once I had seen him walk into a mining power plant on Callisto and disarm a runaway pile that was due to explode in three minutes and blast away half the moon.

Mrs. Campbell, we discovered, had checked in at the Majestic Hotel for one week, and left, giving no forwarding address. After that she had been heard from in two or three of the border cities. She had made the rounds of all the beauty parlors and quack establishments in town. This was her fourth trip to Venus, and all of the merchants knew her by sight. But she was not, currently, visiting any of these places. It seemed that Althea Campbell, a couple of days
