Mrs. Chepstow came out of the house in Cleveland Square as the clocks were striking seven, stepped into a taximeter cab, and was hurried off into the busy whirl of St. James's Street, while Doctor Meyer Isaacson went upstairs to his bedroom to rest and dress for dinner. His clothes were already laid out, and he sent his valet away. As soon as the man was gone, the Doctor took off his coat and waistcoat, his collar and tie, sat down in an arm-chair by the open window, leaned his head against a cushion, shut his eyes, and deliberately relaxed all his muscles. Every day, sometimes at one time, sometimes at another, he did this for ten minutes or a quarter of an hour; and in these moments, as he relaxed his muscles, he also relaxed his mind, banishing thoughts by an effort of the will. So often had he done this that generally he did it without difficulty; and though he never fell asleep in daylight, he came out of this short rest-cure refreshed as after two hours of slumber.

But to-day, though he could command his body, his mind was wilful. He could not clear it of the restless thoughts. Indeed, it seemed to him that he became all mind as he sat there, motionless, looking almost like a dead man, with his stretched-out legs, his hanging arms, his dropped jaw. His last patient was fighting against his desire for complete repose, was defying his will and conquering it.
