Before ten o'clock next morning he was riding to Strathleckie. On reaching the house he asked at once if he could see Mr. Stretton. The maid-servant who answered the door looked surprised, hesitated a moment, and then asked him to walk in. He followed her, and was not surprised to find that she was conducting him straight to the school-room, which was on the ground-floor. He had thought that she looked stupid; now he was sure of it. But it was a stupidity so much to his advantage that he mentally vowed to reward it by the gift of half-a-crown when he had the opportunity.
The boys were at their lessons; their tutor sat at the head of the table, with his back towards the light. When he saw Hugo enter, he calmly took a pair of blue spectacles from the table and fixed them upon his nose. Hugo admired the coolness of the action. The blue spectacles were even a better disguise than the grey hair and the beard; if Mr. Stretton had worn them when he was standing at the railway station door, Hugo would never have been haunted by that look of recognition in his eyes.
"Mary has made a mistake," said Mr. Stretton to one of the boys, in a curiously-muffled voice. "Take this gentleman up to the drawing-room, Harry."
"There is no mistake," said Hugo, suavely. "I called to see Mr. Stretton on business; it will not take me a moment to explain. Mr. Stretton, may I ask whether you have lost any paper—a letter, I think—during the last few days?"
"Yes. I lost a letter yesterday afternoon."
"On the high road, I think. Then I was not mistaken in supposing that a paper that the wind blew to my feet this morning, as I was strolling down the road, belonged to yourself. Will you kindly open this envelope and tell me whether the paper contained in it is yours?"
Mr. Stretton took the envelope and opened it without a word. He looked at the sheet, saw that one only was there, and then replied.
"I am much obliged to you for your kindness. Yes, this is part of the letter that I lost."
"Only part? Indeed, I am sorry for that," said Hugo, with every appearance of genuine interest. "I was first attracted towards it because it looked like a foreign letter, and I saw that it was written in Italian. On taking it up, I observed that it was addressed to a Mr. Stretton, and I could think of no other Mr. Stretton in the neighbourhood but yourself."
"I am much obliged to you," Mr. Stretton repeated.
