"Just what I say. Suppose for convenience we call them ha'nt number one, and ha'nt number two. Number one occupied apartments over the grain bin and haunted the laurel walk. He was white--I don't wonder at that if he spent much time crawling over those flour sacks. He smoked cigars and read French novels; Mose waited on him and Radnor knew about him--and didn't get much enjoyment out of the knowledge. It took money to get rid of him--a hundred dollars down and the promise of more to come. Radnor himself drove him off in the carriage the night he left, and Mose obliterated all traces of his presence. So much for number one. "As for number two, he appeared three or four days before the robbery and haunted pretty much the whole place, especially the region of the spring-hole. In appearance he was nine feet tall, transparent, and black. Smoke came from his mouth and blue flames from his eyes. There was a sulphurous odor about him. He was first seen rising out of the spring-hole, and there is a passage in the bottom of the spring-hole that leads straight down to hell. Solomon is my authority. "I asked him how he explained the apparition and he reckoned it was the ghost of the slave who was beaten to death, and that since his old master had come back to haunt the laurel walk, he had come back to haunt his old master. That sounds to me like a plausible explanation. As soon as it's light I'll have a look at the spring-hole." "Terry," I said disgustedly, "that may make a very picturesque newspaper story, but it doesn't help much in unravelling the mystery." "It helps a good deal. I would not like to swear to the flames or sulphur or the passage down to hell, but the fact that he was tall and black and comes from the spring-hole is significant. He was black--mark that--so were the stolen lap robes. "Now you see how the matter stands on the night of the robbery. While ghost number one was out driving with Radnor, ghost number two entered the house through the open library window, found the safe ajar and helped himself. Let's consider what he took--five thousand dollars in government bonds, two deeds, an insurance policy, and a quart of small change--a very suggestive lot of loot if you think about it enough. After the robbery he disappeared, nothing seen of him for five or six days; then he turned up again for a day or so, and finally disappeared forever. So much for ha'nt number two. He's the party we're after. He pretty certainly robbed the safe and he possibly committed the murder--as to that I won't have any proof until I see the cave." He stretched his arms with a laugh. "Oh, this isn't so bad! All we've got to do now is to identify those two ghosts." "I'm glad if you think it's so easy," I said somewhat sullenly. "But I will tell you one thing, if you go to basing any deductions on Solomon's stories you'll find yourself bumping against a stone wall." "We'll have Rad over to dinner with us tomorrow night," Terry declared.
