From the gateway the mark of the cycle could be traced with ease away towards Burghfield; indeed, a few yards from where the unknown person had apparently met her there were marks of her quick footsteps where she had dismounted. For fully a quarter of an hour the detectives searched both inside and outside the gate trying to distinguish accurately the footprints of the stranger whom she had met, and in this they were actively assisted by the village constable and George, all being careful not to tread upon the weeds and dust themselves. But to distinguish traces of footprints at night is exceedingly difficult; therefore they searched long and earnestly without any success, until at last something half-hidden in some long rank weeds caught George’s eye.

“Why, what’s this?” he cried, excitedly, as putting out his hand he drew forth a purely feminine object—an ordinary black hairpin.

The detectives, eager for anything which might lead to the discovery of the identity of the assassin, took it, examining it closely beneath the light of one of their bull’s-eyes. It was a pin of a common kind, and what at first seemed like a clue was quickly discarded, for on taking it back to where the body was lying and taking one of the pins that held the unfortunate girl’s wealth of fair hair, it was at once seen in comparison to be of the same thickness and make, although of a slightly different length.

Half a dozen pins were taken one by one from her hair and compared, but strangely enough all were about half an inch shorter than the one discovered by George.

“Anything in this, do you think?” one of the detectives asked the other, evidently his superior.

“No,” the man answered promptly. “Women often use hairpins of different lengths. If you buy a box they are often of assorted sizes. No, that pin evidently fell from her hair when she put up her hands to tidy it, after dismounting.”

So the vague theory that the person who joined her was a woman was dismissed. George had said nothing of his appointment with Liane at that spot, deeming it wiser to keep his secret, yet he was sorely puzzled by the fact that Nelly should have been there at the same hour that Liane had arranged to meet him. Perhaps his well-beloved had sent her with a message, as she had on previous occasions. If not, why had she returned from Burghfield by that lonely lane instead of riding direct along the high road, which was in so much better condition for cycling? He had only known her to ride along Cross Lane once before. Indeed, both she and Liane had always denounced that road with its flints and ruts as extremely injurious to cycles.

The assassin had got clean away without leaving the slightest trace. Even his footsteps were indistinguishable where all others were plainly marked, for during the day the dust had been blowing in clouds, carpeting the unfrequented lane to the depth of nearly half an inch, so that every imprint had been faithfully retained.

The detectives, after spending nearly two hours in futile search, were compelled at length to acknowledge themselves baffled, and preparations were made to acquaint Captain Brooker with the sad news, and to remove the body of Nelly Bridson to his house. At first it was suggested that George should go and break the sad tidings to the Captain, but he at once declined. He had never yet met Captain Brooker, and shrank from the unpleasantness of such a first interview with the man whose daughter he intended marrying. The duty therefore devolved upon the police, and the village constable was despatched with strict injunctions from George not to tell Miss Liane, but request to see the Captain himself alone. He knew what a blow it must prove to his well-beloved to thus lose under such terrible circumstances the fair-faced girl who had been her most intimate companion and confidante through so many years; therefore he endeavoured to spare her any unnecessary pain. Her father would, no doubt, break to her the sad truth best of all.

George thought it useless to seek her that night, therefore when the constable had left he took a long farewell glance at the white upturned face, and mounting, turned the mare’s head towards the Court. Onward he rode in the darkness across the open country to Broomfield Hatch, then turning to the right into the Grazely Road, cantered down the hill towards the lodge gates of Stratfield Court.
