'Perhaps,' Mary admitted; and for a moment her misery was rendered even more intense by the thought that possibly that might be the truth. She had hardly yet had time to assimilate the idea that Barney was some sort of detective. If he was, that explained many things. On the assumption that he was a playboy whose time was his own, she had bitterly resented what she had believed to be his lies about his Kenya travel agency arrangements interfering with their meetings; but that, she realized now, could have been cover for periods when he had to perform certain duties. It also excused his taking a title as a pseudonym, as doing so would have made him more readily acceptable at Mrs. Wardeel's. It even made it probable that he had not deliberately let her down the previous week-end to go off with some other woman. As against that there did seem to be a possibility that from the very beginning he had been making use of her only because she had got in with Ratnadatta before he had, and had succeeded in penetrating the Satanic circle at Cremorne.

After only the briefest consideration Mary thrust that last idea aside. Had there been any foundation for it Barney would have urged her to go through with her initiation, then pumped her about what had taken place. As it was he had used his utmost endeavours to persuade her to have no more to do with the Satanists. So if he was a detective he had put her safety before his duty as an investigator. At this thought, in spite of the harsh words with which they had parted, her heart both warmed towards him and was wrung afresh with terrible visions of what lay in store for him.

Virtually a prisoner as she was, she could think of no way in which she could save him or help him to escape, until Wash remarked, 'There's times when you British can be mighty sly. Who'd have thought that for special missions Scotland Yard would have kept on its pay-roll a real live Lord?'

Seizing the opening given her, Mary said quickly, 'I can't believe they do. There's a mistake somewhere. There must be. This fellow is Lord Larne all right. If he had been a fake someone at Mrs. Wardeel's would have been certain to have found him out and exposed him. He is an Irish Earl and only on a visit to England. He has estates in Kenya and has lived there most of his life, so he can't possibly be a member of the British Police Force. The Great Ram must have mistaken him for someone else.'
