“Well,” said Hawkins, “I used to drive an old hansom cab in those days, and I used to drive Paul out on those private calls to the swell houses. And then when Mrs. Paul died and Paul closed up the shop here he kind of drew himself into his shell all round, and mostly he wouldn't go out any more, though the swells kept telephoning and telephoning him. He'd only go to just a few people that he'd done business with since almost the beginning. He said he didn't want to go around ringing people's doorbells, and being ushered into boudoirs or anywhere else, and he was settling down to shun everybody and everything. It wasn't good for Paul. And then a sort of crazy notion struck me, and I chewed it over and over in my mind, and finally I put it up to Paul. In the mood he was in, it just caught his fancy; and so I bought a second-hand closed car, and fitted it up like you saw, and learned to drive it--and that's how there came to be the traveling pawn-shop. “After that, there wasn't anything to it. It caught everybody else's fancy as well as Paul's, and it began to get him out of himself. The old bus, as you called it, was running all the time. Lots of the swells who really didn't want to pawn anything took a ride and did a bit of business just for the sake of the experience, and the regular customers just went nutty over it, they were that pleased. “And then some one who stood in with that swell gambling joint where we picked you up must have tipped the manager off about it, and he saw where he could do a good stroke of business--make it a kind of advertisement, you know, besides doing away with any lending by the house itself, and he put up a proposition to Paul where Paul was to get all the business at regular rates, and a bit of a salary besides on account of the all-night hours he'd have to keep sometimes. Paul said he'd do it, and turned the salary over to me; and they doped out that pass word about a trip to Persia to make it sound mysterious and help out the advertising end, and--well, I guess that's all.” John Bruce was twirling the tassel of his dressing gown again abstractedly; but now he stopped as Hawkins rose abruptly and came toward him. “No--it ain't all,” said Hawkins, a curious note almost of challenge in his voice. “You said something about Claire going to that gambling joint. It was the first time she had ever been there. That night Paul was out when they telephoned. You must be one of their big customers, 'cause they wouldn't listen to anything but a trip to Persia right on the spot. They were so set on it that Claire said it would be all right. She sent for me. At first I wasn't for it at all, but she said it seemed to be of such importance, and that there wasn't anything else to do. Claire knows a bit of jewelry or a stone as well as Paul does, and I knew Claire could take care of herself; and besides, although she didn't know it, it--it was her own old father driving the car there with her.”
