The mystery was deepening in an alarming fashion, and its intricacies were such as did not conduce to quiet sleep. That he had at last actually encountered his father's enemy he was quite convinced, but he was no nearer being able to account for the strange creature's enmity or even to recognise its identity than before he had met with this last adventure.

A few facts about the unknown creature were very apparent. Firstly, it was strangely agile and cunning; secondly, its voice was as remarkable as its agility, which was hardly human; thirdly, it was in possession of a bicycle, and yet was unable to obtain food and clothing without having recourse to theft; fourthly, it was of peculiarly small stature for a man; and lastly, it was able to use firearms, but with the loss of the pistol it had probably been deprived of its only offensive weapon, since it had not ventured to attack its assailant in the barn.

Laurence used the word "it" because he was in no way decided in his own mind as to whether the thing was a man, a woman, or, the idea occurred to him, neither of these two. Not that he believed it to be something that was not human, but because the marvellous manner in which it had scaled the barn walls was so suggestive of the monkey race. The idea that the creature in the barn was a species of monkey he at once decided, of course, to be absurd. A monkey might have stolen the missing coat and dinner, have thrown the hay down in order to cover its retreat, and have uttered that piercing shriek on being hurt, but it was hardly likely to be able either to ride a bicycle or use a pistol.

That it was a woman was more possible, and the young investigator's foundation for the idea was the remark of Miss Scott that her friend had declared the person lurking in the Marquis's garden to be a black woman "with coloured skirts." This remark, it will be remembered, was very probably the cause of the Squire's sudden illness at luncheon, shortly after the arrival of Mrs. Knox and her niece.

A woman might have performed all the feats that the unknown person had. She might have set light to the Marquis's house, believing the Squire to be yet in the building; she might have followed the carriage on a bicycle on discovering that the man she was dogging had left (though how she came to have a bicycle was a mystery in itself); she might have "held up" the carriage and attempted to murder the old gentleman; and it was just as possible (or impossible) for her to clamber up the barn wall as for a man to do so. To be sure, she must be a very remarkable woman. Since she was "black," she might be a negress or certainly some foreigner. Uncivilised and fierce she certainly was. But how came it that a negress (if such were the case) had so bitter an enmity against the harmless old Squire that it was the cause of all Mr. Carrington's careful precautions, and of the spirited attack on the high road? The mystery seemed hopelessly incapable of solution.

Morning came at last, and found Laurence no further advanced with his investigations. At one time he had decided to summon a detective, but recollecting how the Squire would take such an intrusion he considered it advisable to work alone.

What the relations of the woman (suppose it to be a woman) in the barn and the disguised man who had purchased the dog whip were, he had not yet ventured to guess, but one thing was quite plain: they were in some way connected.

A fruitless effort had been made to attempt the solution of the problem through the "woman" servant in the Dene. Equally impossible would it be to obtain any information from the Squire. The idea of conversing in any way with the woman (?) in the barn (even if she were yet hiding there) was more than ridiculous. Consequently, the original scheme was the only one left which seemed in any way possible.

Laurence felt that the sole remaining course open to him was to interview "Major Jones-Farnell"!

During breakfast (at which meal the Squire did not appear) he cast all meditation and worry aside for the time being, and set himself to the task of entertaining the two ladies. Mrs. Knox, however, wanted little entertainment. A good breakfast was quite sufficient for her!
