The smile slipped. He turned his head and looked into the complacent, chubby face and the pleased eyes of M. J. Brock, head of Brock's Detective Agency--the man of all men in this world he wished least to see. For once, anyhow, in his life Marr was shaken, and showed it. "That's all right, Chappy," said Brock soothingly, rocking his short plump figure on his heels; "there won't be any rough stuff. I've got a cop off the corner who's waiting outside if I should need him--in case of a jam--but I guess we won't need him, will we? You'll go along with me nice and friendly in a taxicab, won't you?" He flirted his thumb over his shoulder. "And you needn't bother about Gulwing either. I've seen him--saw him as soon as I came in. I guess he'll be seeing me in a minute, too, and then he'll suddenly remember where it was he left his umbrella and take it on the hop." Marr said not a word. Brock rattled on in high spirits, still maintaining that cat-with-a-mouse attitude which was characteristic of him. "Never mind worrying about old pal Gulwing--I don't want him now. You're the one you'd better be worrying about; because that's going to be a mighty long taxi ride that you're going to take with me, Chappy--fifteen minutes to get there, say, and anywhere from five to ten years to get back--or I miss my guess.... Yes, Chappy, you're nailed with the goods this time. Propbridge is going through; his wife too. They'll go to court; they'll shove the case. And Cheesy Zaugbaum has come clean. Oh, I guess it's curtains for you all right, all right." "You don't exactly hate yourself, do you?" gibed Marr. "Sort of pleased with yourself?" "Not so much pleased with myself as disappointed in you, Chappy," countered the exultant Brock. "I figured you were different from the rest of your crowd, maybe; but it turns out you're like all the others--you will do your thinking in a groove." He shook his head in mock sorrow. "Chappy, tell me--not that it makes any difference particularly, but just to satisfy my curiosity--curiosity being my business, as you might say--what number was it you called up from here about thirty minutes back? Come on. The young lady over yonder will tell me if you don't. Was it Worth 10,000?" "Yes," said Marr, "it was." "I thought so," said Brock. "I guessed as much. But say Chappy, that's the trunk number of the Herald. Before this you never were the one to try to break into the newspapers on your own hook. What did you want with that number?" "That's my business," said Marr.
