"Is that about the governor?" he asked.

Arnold nodded.

"It was Mrs. Weatherley speaking," he said. "It seems Mr. Weatherley left Bourne End soon after seven o'clock this morning."

"Soon after seven o'clock?" Mr. Jarvis repeated.

"The car has been back there quite a long time," Arnold continued. "Mrs. Weatherley has gone to make inquiries of the chauffeur."

"Most extraordinary thing," Mr. Jarvis muttered. "I can't say that I've ever known the governor as late as this, unless he was ill."

Arnold put the receiver once more to his ear. In a moment or two Mrs. Weatherley returned. Her voice was a little graver.

"I have spoken to the chauffeur," she announced. "He says that they called first up in Hampstead to see if there were any letters, and that afterwards he drove Mr. Weatherley over London Bridge and put him down at the usual spot, just opposite to the London & Westminster Bank. For some reason or other, as I dare say you know," she went on, "Mr. Weatherley never likes to bring the car into Tooley Street. It was ten minutes past nine when he set him down and left him there."

Arnold glanced at the clock.

"It is now," he said, "a quarter to eleven. The spot you speak of is only two hundred yards away, but I can assure you that Mr. Weatherley has not yet arrived."
