pardon, sir," she began, "but I thought I ought to tell you that when cook and me was going out to the concert last night we thought we saw something in the drive."

Mr. Rattar looked up at her sharply and fixed his cold eyes on her steadily for a moment, never saying a word. It was exactly his ordinary habit, and she had thought she was used to it by now, yet this morning she felt oddly disconcerted. Then it struck her that perhaps it was the red cut on his chin that gave her this curious feeling. Silent Simon's hand was as steady as a rock and she never remembered his having cut himself shaving before; certainly not as badly as this.

"Saw 'something'?" he repeated gruffly. "What do you mean?"

"It looked like a man, sir, and it seemed to move into the trees almost as quick as we saw it!"

"Tuts!" muttered Simon.

"But there was two friends of ours meeting us in the road," she hurried on, "and they thought they saw a man going in at the gate!"

Her master seemed a little more impressed.

"Indeed?" said he.

"So I thought it was my duty to tell you, sir."

"Quite right," said he.

"For I felt sure it couldn't just be a gentleman coming to see you, sir, or he wouldn't have gone into the trees."

"Of course not," he agreed briefly. "Nobody came to see me."

Mary looked at him doubtfully and hesitated for a moment.

"Didn't you even hear anything, sir?" she asked in a lowered voice.

Her master's quick glance made her jump.

"Why?" he demanded.

"Because, sir, I found footsteps in the gravel this morning—where it's soft with the rain, sir, just under the library window."

Mr. Rattar looked first hard at her and then at his plate. For several seconds he answered nothing, and then he said:

"I did hear some one."

There was something both in his voice and in his eye as he said this that was not quite like the usual Simon Rattar. Mary began to feel a sympathetic thrill.

"Did you look out of the window, sir?" she asked in a hushed voice.

Her master nodded and pursed his lips.

"But you didn't see him, sir?"

"No," said he.

"Who could it have been, sir?"

"I have been wondering," he said, and then he threw a sudden glance at her that made her hurry for the door. It was not that it was an angry look, but that it was what she called so "queer-like."

Just as she went out she noted another queer-like circumstance. Mr. Rattar had stretched out his hand towards the toast rack while he spoke. The toast stuck between the bars, and she caught a glimpse of an angry twitch that upset the rack with a clatter. Never before had she seen the master do a thing of that kind.

A little later the library bell called her. Mr. Rattar had finished breakfast and was seated beside the fire with a bundle of legal papers on a small table beside him, just as he always sat, absorbed in work, before he started for his office. The master's library impressed Mary vastly. The furniture was so substantial, new-looking, and conspicuous for the shininess of the wood and the brightness of the red morocco seats to the chairs. And it was such a tidy room—no litter of papers or books, nothing ever out of place, no sign even of pipe, tobacco jar, cigarette or cigar. The only concession to the vices were the ornate ash tray and the massive globular glass match box on the square table in the middle of the room, and they were manifestly placed there for the benefit of visitors merely. Even they, Mary thought, were admirable as ornaments, and she was concerned to note that there was no nice red-headed bundle of matches in the glass match box this morning. What had become of them she could not imagine, but she resolved to repair this blemish as soon as the master had left the house.

"I don't want you to go gossiping about this fellow who came into the garden, last night," he began.

"Oh, no, sir!" said she.

Simon shot her a glance that seemed compounded of doubt and warning.

"As procurator fiscal, it is my business to inquire into such affairs. I'll see to it."

"Oh, yes, sir; I know," said she. "It seemed so impudent like of the man coming into the fiscal's garden of all places!"

Simon grunted. It was his characteristic reply when no words were absolutely necessary.

"That's all," said he, "don't gossip! Remember, if we want to catch the man, the quieter we keep the better."

Mary went out, impressed with the warning, but still more deeply impressed with something else. Gossip with cook of course was not to be counted as gossip in the prohibited sense, and when she returned to the kitchen, she unburdened her Highland heart.

"The master's no himsel'!" she said. "I tell you, Janet, never have I seen Mr. Rattar look the way he looked at breakfast, nor yet the way he looked in the library!"

Cook was a practical person and apt to be a trifle unsympathetic.

"He couldna be bothered with your blethering most likely!" said she.

"Oh, it wasna that!" said Mary very seriously. "Just think yoursel' how would you like to be watched through the window at the dead of night as you were sitting in your chair? The master's feared of yon man, Janet!"

Even Janet was a little impressed by her solemnity.

"It must have taken something to make silent Simon feared!" said she.

Mary's voice fell.

"It's my opinion, the master knows more than he let on to me. The thought that came into my mind when he was talking to me was just—'The man feels he's being watched!'"

"Oh, get along wi' you and your Hieland fancies!" said cook, but she said it a little uncomfortably.

THE HEIR

At 9.45 precisely Mr. Rattar arrived at his office, just as he had arrived every morning since his clerks could remember. He nodded curtly as usual to his head clerk, Mr. Ison, and went into his room. His letters were always laid out on his desk and from twenty minutes to half an hour were generally spent by him in running through them. Then he would ring for Mr. Ison and begin to deal with the business of the day. But on this morning the bell went within twelve minutes, as Mr. Ison (a most precise person) noted on the clock.

"Bring the letter book," said Mr. Rattar. "And the business ledger."

"Letter book and business ledger?" repeated Mr. Ison, looking a little surprised.

Mr. Rattar nodded.

The head clerk turned away and then paused and glanced at the bundle of papers Mr. Rattar had brought back with him. He had expected these to be dealt with first thing.

"About this Thomson business—" he began.

"It can wait."

The lawyer's manner was peremptory and the clerk fetched the letter book and ledger. These contained, between them, a record of all the recent business of the firm, apart from public business and the affairs of one large estate. What could be the reason for such a comprehensive examination, Mr. Ison could not divine, but Mr. Rattar never gave reasons unless he chose, and the clerk who would venture to ask him was not to be found on the staff of Silent Simon.

In a minute or two the head clerk returned with the books. This time he was wearing his spectacles and his first glance through them at Mr. Rattar gave him an odd sensation. The lawyer's mouth was as hard set and his eyes were as steady as ever. Yet something about his expression seemed a little unusual. Some unexpected business had turned up to disturb him, Mr. Ison felt sure; and indeed, this seemed certain from his request for the letter book and ledger. He
