"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.
He rose and pulled out his watch.
"It's a quarter before ten. I think it's time you went to bed. You look about played out. You haven't been sleeping much of late?"
"No, I can't say that I have."
"I ought to have come down at once," said Terry, "but I'm always so blamed afraid of hurting people's feelings."
