Simon finished his meal and returned to the office, noticing already the premonitory symptoms of the mild indigestion that habitually followed the greasy cooking of the hotel chef. He found his insurance man waiting for him and spent two tedious hours over an inventory and proofs of loss before he could rid himself of the fellow—and sped his going with a curse because the broker warned him the insurance company would certainly cancel their existing policies if they got wind of an incendiary.

That reminded Simon of the footprints in the tannery yard which he had wished to examine by daylight. He had intended to show them to that chap Krech, but Jason had spoiled things by hurrying him off to his silly lunch. He descended the stairs, called Nelson to join him, and went to the end of the fence around which the fire bug had fled.

He gave the watchman a brief account of Fay's experience at the commencement of the fire, when he had actually obtained a glimpse of the incendiary at his evil work. He discussed with Nelson, a shrewd man, the possible identity of the miscreant, but they arrived at no conclusion. Together they traced the footprints from the yard around the fence and up the muddy bank of the little stream until they vanished on the firmer ground outside the premises.

"Make anything of them?" asked Varr.

"Nothing more than you do, sir; they seem to be the tracks of a large man. That friend of Mr. Bolt's could have made 'em nicely."

"Get a couple of empty boxes," directed Simon, mindful of the protective device he had used in his kitchen garden to preserve the marks left by Charlie Maxon. "Cover up two good sets of these; they may come in handy later." He studied the skies. "We'll probably have rain before morning."

"Fay won't object to that," declared the watchman, grinning. "If he had his wish, it would rain chemical fire-extinguishing fluid!"

Simon lingered to see that the work of covering the tracks was properly done, and hoped that Mr. Krech and his detective would appreciate his thoughtfulness. Then he left the tannery, climbed into his car and drove home. The strain of the night before had told on even his iron physique—and there was the mute appeal of a decanter of Bourbon that he knew would freshen his nagging spirit.

Jason's dilapidated little touring car greeted his gaze as he drove past the front of the house to the garage, and a sound of light voices came to him from the side veranda. Easy enough to guess the meaning of that, the Bolts had dropped in with their friends for tea and a chat with Lucy, who counted Mary Bolt her closest friend.

He joined them a moment later. Lucy, he saw at once, had been crying. No amount of powder or superficial gayety could conceal that fact from him. She did not look at him directly, and her voice was frigid as she introduced him to the one member of the party he had not met.
