Rosewarne laughed grimly. "You're right there, and I've often enough asked myself why I do it. To what end, good Lord! But I'm taking no care, all the same. Good-bye."

"Good-bye, my friend." The doctor did not remonstrate further. He knew his man.

From Lockyer Street Rosewarne walked to his hotel, ordered a beef-steak and a pint of champagne, and lunched leisurably. Lunch over, he lit a cigar, and strolled in the direction of the Barbican. The streets were full of holiday-keepers, and he counted a dozen brakes full of workers pouring out of town to breathe the air of Dartmoor on this fine afternoon. He himself was conscious of elation.

"I'll drink it regularly," he muttered to himself. "It's hard if a man with maybe a month more to live cannot afford himself champagne."

The air in Southside Street differed from that of Dartmoor, being stuffy, not to say malodorous. He rapped on the door of a dingy office, and it was opened by his son, Mr. Samuel Rosewarne.

"How d'ye do, Sam?" he nodded, not offering to shake hands. "All alone? That's right. I hope, by the way, I'm not depriving you of a holiday?"

"I seldom take a holiday," Mr. Sam answered.

The old man eyed him ironically. Mr. Sam wore a black suit, with some show of dingy white shirt-front, relieved by a wisp of black cravat and two onyx studs. His coat-cuffs were long and frayed, and his elastic-side boots creaked as he led the way to the office.

In the office the old man came to business at once. "First of all," said he, with a nod toward the safe, "I'd like a glance into your books."

"Certainly, sir," answered Mr. Sam, after a moment's hesitation. He unlocked the safe. "Do you wish to take the books in order? You will find it a long business."
