The clerk shook his head. "Never saw him before to my knowledge," he said.
"That, then?" asked Grant, handing over Sorrell's photograph, and the clerk immediately recognized it.
"Did he inquire about his neighbors in the row?" Grant asked. But the clerk could recall no details like that. It had been a very busy day that Monday. Grant thanked him, and went out into the drizzle, quite unaware that it was raining. Things were no longer reasonable and understandable; cause and effect, motive and action decently allied. They were acquiring a nightmare inconsequence that dismayed his daytime brain. Sorrell had intended to go to America, after all. He had booked a second-class passage and personally chosen a cabin. The amazing and incontrovertible fact did not fit in anywhere. It was a very large wrench thrown into the machinery that had begun to run so smoothly. If Sorrell had been as penniless as he seemed, he would not have contemplated a second-class journey to New York, and in view of the booking of the passage, contemplated suicide seemed a poor explanation for the presence of the revolver and absence of belongings. It shouted much more loudly of his first theory — that the lack of personal clues had been arranged in case of a brush with the police. But Sorrell had, to all accounts, been a law-abiding person. And then, to crown things, there was Mrs. Ratcliffe's reappearance in the affair. She had been the only one of the people surrounding Sorrell to show marked distress at the time of the murder or afterwards. It was she and her husband who had avowedly been next behind Sorrell in the queue. Her husband! A picture of James Ratcliffe, that prop of British citizenship, swam into his mind. He would go and have another, and totally unheralded, interview with Mr. Ratcliffe.
The boy took in his card, and he waited in the outer office for perhaps three minutes before Mr. Ratcliffe came out and drew him in with a welcoming affability.
"Well, Inspector," he said, "how are you getting on? Do you know, you and dentists must be the most unhappy people in the world. No one sees you without remembering unpleasant things."
"I didn't come to bother you," Grant said. "I just happened to be round, and I thought you'd perhaps let me use your telephone to save me going to a post office."
"Oh, certainly," said Ratcliffe. "Carry on. I'll go."
"No, don't go," said Grant, "there'll be nothing private. I only want to know whether they want me."
But no one wanted him. The scent in South London was weak, but the hounds were persevering and busy. And he hung up with a relief which was rather surprising when one considered the eager frame of mind in which he had set out from the Yard. Now he did not want an arrest until he had time to think things over for a bit. The nightmare of a Scotland Yard officer's whole life is Wrongful Arrest. He turned to Ratcliffe, and allowed him to know that an arrest was imminent; they had located their man. Ratcliffe was complimentary, and in the middle of the compliments Grant said, "By the way, you didn't tell me that your wife had intended sailing for New York the night after the murder."
Ratcliffe's face, clear in the light of the window, was both blank and shocked. "I didn't know," he began, and then with a rush — "I didn't think it was of any importance or I should have told you. She was too much upset to go, and in any case there was the inquest. She has a sister in New York, and was going over for a month just. It didn't make any difference, did it? Not knowing, I mean? It had no bearing on the crime."
