“Half past dinner time,” he announced. “We’re wasting moments, Gilly. I’ll leave a note here for Morley to say we’ve been here and won’t be back, then we’ll go to luncheon and afterward we’ll transfer our attentions to the more pleasant and lucrative task of aiding Miss Minor.” “But what did you mean by telling that fellow that Vanderdonck had no business?” I asked. “Just that,” was the reply. “He came here as a blind. The whole office shows it. Everything is practically as the dentist left it two years ago. Vanderdonck just moved in. The holes in the floor indicate where the chair of pain used to be, the walls have not been cleaned since the dentist took down his pictures, and the books and magazines for the most part were left there by the old tenant. The place was never intended for occupancy. Vanderdonck came here when it was necessary only. But someone else came here, too—came here and didn’t leave again. The safe will tell the story. I’ll tell Morley enough to make it look like his discovery. But the fact is, Gilly, I’m as sure as I’m here that the safe contains all that is left of Charles Merritt!” I spun about and looked with horror at the great black hideous thing, and a dreadful picture formed in my mind as I seemed to see the door swing open, upon—what? But Lavender, without a shudder, sat down to pen his note to Morley. —— III —— At luncheon I questioned Lavender vigorously, but he had little information to impart. He ate in silence for the greater part of the meal and afterward smoked several thoughtful cigarettes. “I’ve told you practically all I know about the case, Gilly,” was all he said in direct reply to my questions. “And what I know, I know chiefly because it must be so. Of actual evidence I have very little, but there certainly have been many significant indications.” “And now we go back to Miss Minor and her troubles?” “Exactly! You’ve no objections to going back to Miss Minor, surely?” I laughed. “None in the world. I like her very much. But what did you say in your note to Morley, Lavender?” “Just this: Morley, open safe at earliest opportunity. It contains the solution of two mysteries. See morning papers. Now will you call a taxi?” On that we fared forth to attack the problem we, or at any rate Lavender, had been employed to solve. As we drove north across the Loop in a swirling ocean of traffic my mind became occupied with thoughts of the charming young person we were going to see, and I looked forward with pleasure to our second meeting. Lavender, whatever his thoughts were, smoked many cigarettes and drummed impatiently with his fingers on the narrow window ledge. When he had finished with one cigarette, he lighted another from the glowing tip of the old one and resumed his drumming. I supposed him to be in deep thought.
