"Do you know his home address?" asked Grant.

"No. Who wants him? He's a good boy, Sorrell."

The last irrelevance seemed to suggest suspicion, and Grant hastened to assure him that no harm was intended Sorrell. At that Thacker put his first and second fingers into either corner of his mouth and emitted a shrill whistle in the direction of the railings at the edge of the course. From the crowd of attentive faces which this demonstration had turned towards him he selected the one he wanted. "Joe," he said in stentorian tones, "Let me speak to Jimmy a minute, will you?" Joe detached his clerk, as one detaches a watch and chain, and presently Jimmy appeared a clean, cherubic youth with an amazing taste in linen.

"You used to be pally with Bert Sorrell, didn't you?" asked Thacker.

"Yes, but I haven't seen him for donkey's years."

"Do you know where he lives?"

"Well, when I knew him he had rooms in Brightling Crescent, off the Fulham Road. I've been there with him. Forget the number, but his landlady's name was Everett. He lived there for years. Orphan he was, Bert."

Grant described the Levantine, and asked if Sorrell was ever friendly with a man like that.

No, Jimmy had never known him in such company, but then, as he pointed out, he hadn't seen him for donkey's years. He had dropped out of the regular crowd when he started on his own, though he sometimes went racing for his own amusement or perhaps to pick up information.

Through Jimmy, Grant interviewed two more people who had known Sorrell; but neither could throw any light on Sorrell's companions. They were self-absorbed people, these bookmakers, looking at him with a vague curiosity and obviously forgetting all about him the minute their next bet was booked. Grant announced to Murray that he had finished, and Murray, whose interest had waned with the finish of the handicap hurdle, elected to go back to town at once. But as the car slid slowly out of the press Grant turned with a benedictory glance at the friendly little course which had provided him with the information he sought. Pleasant place. He would come back some day when he had no business on his mind to bother him, and make an afternoon of it.
