"And let me know by some messenger who can ride as fast as I can." Then adding, "Gilderoy was saved by a brown mouse, which gnawed the string by which the key of the jail door of Forfar hung on a nail, whereby the key fell to the ground, and was pulled by him through an opening at the bottom. Heard you ever the story?"

"No."

"But it's true, nevertheless. What would you say if a white mouse, or two of them, should save the life of your wife?"

"I would say it was wonderful," replied the farmer, with eyes a-goggled by amazement.

"And so would I," answered Mr. M——, as he put the rowels into the side of his horse and began a hard trot, which he would not slacken till he was at the Cowgate port, and not even then, for he made his way generally through the streets of the town with equal rapidity, and always the safer that he was the "fresher."

On arriving at his office he sat down, and, without apparently any premeditation, unless what he had indulged in during his trot, wrote off with his usual rapidity four letters to the following effect:—"Dear Sir,—As agent for Mrs. S——, who now lies in our jail on a charge of murder, I request you will endeavour to find some trace of a woman who goes through the country with a cage and two white mice. Grave suspicions attach to her, as the person who administered the poison, and I wish your energies to be employed in aiding me to search her out." The letters were directed to agents in Arbroath, Forfar, Kirriemuir, and Montrose, and immediately committed to a clerk to be taken to the post-office, with a good-natured laugh on the lips of the writer—and, within the teeth, the little monologue—"The wrinkled skin easily conceals a scar."

From some source or another, probably the true one may be guessed, an uberrima fides began to hang round a report that a new feature had spread over the face of Mrs. S——'s case; and that, in place of her being the guilty person, the culprit was a tramp, with white mice in a cage. Nor were the authorities long in being startled by the report; but where that woman was no one could tell, and a vague report was no foundation for authoritative action. But if it was not for a Lord Advocate to seek out or hunt after white mice, that was no reason why the prisoner's agent should not condescend to so very humble an office; and, accordingly, two days after the despatch of the letters I have mentioned, the same horse that carried the writer on the former occasion, and knew so well the prick of his rowels, was ready saddled at the door of the office. The head of the agent was instantly drawn out of some other deep well of legal truth, some score of directions given to clerks, and he was off on the road to Glammis, but not before some flash had shown him what he was to do when he got there. The same rapid trot was commenced, and continued, to the great diminution of the sap of the animal, until the place he was destined for loomed before him. He now commenced inquiries upon inquiries. Every traveller was questioned, every door got a touch of his whip, until at length he got a trace, and he was again in full pursuit. I think it is Suidas who says that these pretty little animals, called white mice, are very amatory, and have a strong odour, but this must be only to their mates. I doubt if even the nostrils of a writer are equal to this perception, whatever sense they may possess in the case of pigeons with a pluckable covering. But, however this may be, it was soon observable that our pursuer had at least something in his eye. The spurs were active; and, by and by, he drew up at a small road-side change-house, into the kitchen of which he tumbled, without a premonitory question, and there, before him, sat the veritable mistress of these very white mice, spaeing the fortunes of some laughing girls, who saw the illuminated figures of their lovers in the future.[1]

[1] One version of the story says that Mr. M—— picked up the tramp at Cammerton, in Fife; but I adhere to my authority.

"Can you read me my fortune?" he said, in his own peculiar way.

"Na; I ken ye owre weel," was the quick reply, as she turned a pair of keen, grey eyes on him.
