Mostly, however, he had spent his time in an upstairs room which had once been a nursery, for it had iron bars at the window. His eyes sought that window—and he found it!

Ah! in that room he had spent many dreary hours; his mind filled with weird and horrible visions—shadowy pictures which seemed bent on driving him to insanity.

For fully a quarter of an hour he remained in the vicinity, his eyes strained on every side, and gradually recovering his normal memory.

When, however, he tried to recall that night when he had acted under the overbearing influence of the woman Crisp he, alas! failed—failed utterly. Perhaps if he could get sight of the interior of the room in which he was victimised he might remember, but strive how he would all he could recall was but misty and unreal.

At last he turned from the house, half-fearful lest his presence there might be known, yet gratified that the place was shut up.

Had the woman and her companion left? Had they taken fright and flown?

He walked back to the station, but ere he had arrived at King’s Cross he found that his recollection was becoming fainter, until it was just as hazy as before. Only when his eyes were fixed upon the scene of his mysterious bondage did his memory return to him.

Yet he had satisfactorily cleared up one important point. He had fixed the house to which he had been secretly conveyed. Had the girl Edna Manners been taken there also? Perhaps her body had afterwards been concealed. Recollection of his mysterious discovery caused him to shudder. The girl’s appeal to him to save her still sounded in his ears, while the vision of that pale, still countenance often rose before him.

Next day, and the next, he was busy purchasing the wireless set which he had promised to obtain for Mr Sandys—a seven-valve Marconi set with a “double note-magnifier,” a microphone relay and a loud-speaking telephone. This, with coils taking every wavelength from one hundred to twenty-five thousand metres, completed one of the best and most sensitive sets that had been invented.

Adjoining the morning-room in the east wing of Farncombe Towers was a small ante-room, and into this he proceeded to instal the apparatus, aided of course by Elma. Mr Sandys had gone to Paris to consult with his partner, therefore the young pair had the place to themselves.
