"But my master would have sent anything you had asked for!" exclaimed Caw.

"I did not doubt it. Only, you see, I was desperately afraid of my existence getting known, and—"

"But why?"—from the impulsive Marjorie.

"An obsession, if you like," said Alan with a grave smile. "During all the time of my convalescence, and in all the periods of leisure that followed, I kept wondering what on earth had made Flitch want to kill me. We had never had anything like a quarrel, and what had he to gain by my death? He had robbed me of nothing. It's a great big 'Why,' and I've got to find the answer to it. But I'm keeping you from bed."

"Go ahead," said Handyside. "Have you no suspicions?"

"I have; but they seem a bit far-fetched, especially now that I'm home. At any rate, I dare not mention them yet…. I arrived in Glasgow this afternoon, and got made as civilised-looking as was possible in a couple of hours. I had intended coming on here by rail and steamer, but an out-of-date time-table deceived me, and too late I found that the winter service just started gave no train after five. At the hotel they suggested motoring, and after a meal I started on what seemed a first rate car. But we had a breakdown lasting an hour, a dozen miles out of Glasgow, and then, running down Garelochside in the face of the storm, we smashed into the ditch. After making sure that the car was hopeless, I left the man at a wayside cottage and tramped the rest of the way. Hence my late arrival, and you know the rest."

"May I ask," said Caw, "if you met anybody on the road—near home, I mean?"

"I passed a person who seemed to be intoxicated, if judged by his violent language, but in the darkness and the rain we must have been practically invisible to each other."

"If he was using bad language, sir," said Caw, rising, "he was certainly not the party I am thinking of. May I retire, gentlemen?" he inquired, glancing towards Miss Handyside.

"Yes, Caw. You will have much to tell Mr. Craig to-morrow," said the doctor. "I leave it to you to explain why you were absent to-night. I doubt I shall never get over it."
