Laurence agreed. The idea, hardly practicable as it seemed to be, was at any rate better than his own of going straight to the seat of the mystery and showing his hand in an interview, which he might or might not be allowed, with Major Jones-Farnell.

Further conversation between the young people decided them that no better means of attempting the solution was possible.

The first question to be decided was where the "tackling," as Laurence called it, of the old woman should take place, how the scheme should be worked, and when it was possible for a start to be made.

For many reasons, the pair argued, it would be as well to set to work as soon as possible, since the first attempt on the Squire's life might at any moment be followed up by a second, and perhaps even more desperate effort.

There could be little doubt but that the position of anyone who attempted to frustrate the hidden enemy's murderous attempts was one of danger, and for this reason Laurence regretted, when too late, that Miss Scott should have elected to share that risk with him. In vain did he suggest that she should not endanger herself in any way, but remain behind the scenes, pulling the strings of the manœuvre by means of her suggestions and ready advice. She would have none of it. She was equally interested in the case as was her companion, and as to any question of endangering her life, she said that she had no fears on that account, since the mere encounter with a harmless old woman was hardly likely to prove a hazardous adventure.

At this stage of the important discussion afternoon tea and Mrs. Knox appeared on the scene, so, for the moment, further conversation on any but ordinary subjects was impossible.

After tea, however, the elder lady, explaining that she had letters to write, again begged to be excused from accompanying the young people. So once more were they at liberty to resume their conversation.

Laurence, in the meantime, had been able, by a judiciously worded question, to learn from the butler that the mysterious woman from the Dene was in the habit of doing her marketing on Tuesday evenings. Since this was a Tuesday, an opportunity would probably arrive very shortly for the proposed encounter with that lady. It was therefore necessary that they should decide their plan of action without delay. And this they proceeded to do, while taking a walk round the orchards, that stretched for half a mile downwards behind the house.

By the time they returned to the Manse it was within an hour of dinner-time, so each hurried away to dress for a long and formal meal, that proved to be somewhat tedious to the young people, very agreeable, owing to its sumptuousness, to good Mrs. Knox, and evidently a mere matter of form to the Squire, who sat motionless in his chair almost from the beginning to the end of dinner, hardly addressing a single word to his guests, or partaking of so much as a taste of the numerous delicacies placed, one after another, before him. It will have already been noticed that Mrs. Knox was not an exemplary chaperon, or perhaps she considered that Selene, or Lena, as the old lady called her, was sufficiently sensible to be able to take care of herself; or it is even possible that she was an expert match-maker. At any rate, she either did not notice, or did not mind, when, at the conclusion of the stately repast, and on the departure of the Squire to his own room, her charge, hurriedly donning a hat and cloak, left the house with Laurence Carrington. Had she known the intentions of the pair, she might have raised some objections, though anything that did not conduce to peace and quiet was hardly to Matilda Knox's liking!

On leaving the grounds of the Manse, taking as they did so a casual glance at the tumble-down, ivy-coated walls of the dingy neighbouring house, the two excited young people turned off towards the lower part of the village, where the few shops that the place boasted were to be found.
