He had made his decision to begin with a past client of his own, a man for whom he had solved a sensitive domestic problem and avoided a situation which could have become very ugly. Mr. Sandeman was correspondingly grateful, and had pronused to give any assistance he was able should Monk ever need it. Monk was not sure if he had spoken impulsively, without any belief that he would ever be taken up on it, but this seemed like an excellent time to put it to the test.

Accordingly, he arrived at Upper Bedford Place just after three o'clock, and asked if he might see Mr. Sandeman on a matter of urgency.

"If it were not, I should not trouble him on a Saturday, and without writing first," Monk explained to the butler, taking off his gloves and passing the man his hat and stick as if there were no question as to whether he would be received.

"Certainly, sir," the butler said, masking his surprise with long practice. "I shall see if Mr. Sandeman is at home." That was the conventional way of saying he would see if the visitor could be welcomed or not. Naturally, he was perfectly aware who was in the house and who was not. It was his job to be. "If you care to wait in the green room, sir, I am sure you will be comfortable."

The green room was very attractive, full of afternoon sunlight from white-painted windows which overlooked a garden where silver birch leaves shimmered in the breeze, making the air seem to dance. Inside the walls were papered with an unusually plain dark green, and two were hung with many paintings of landscapes. Monk remembered the room from his previous visit, when Sandeman had been so concerned about an apparent theft from his wife's bedroom. But that had been satisfactorily dealt with, and it would be tactless to raise the issue now.

Monk had not long to wait. The door opened and Robert Sandeman came in, a look of apprehension on his broad, good-natured face. He was a very wealthy man who continued to look as if he were wearing secondhand clothes, even when they were the best Savile Row could offer. They seemed to have been made for someone of an entirely different shape. He was the despair of his tailors.

"Hello, Monk!" he said with evident surprise. "Nothing new arisen, has it?" He could not keep the anxiety out of his eyes.

"Nothing at all," Monk assured him. "I am looking into another matter entirely, for a friend, and hoped you might be able to give me a little assistance. I have to learn enough to provide some sort of answer by Monday morning, or else I would not have disturbed you like this."

Sandeman's relief was almost palpable. He closed the door behind him and waved at one of the large chairs, sitting in one of the others.
