But Verney had told Barney that he regarded that as most unlikely. From the beginning he had believed that Teddy Morden had died as the victim of a human sacrifice to Satan. There was no factual evidence that he had ever gone to the mansion in Cremorne but the circumstantial evidence that he had done so was too strong not to be accepted. Not only had the nightmares that had afflicted Morden for several weeks before his death been of a nature to indicate very strongly that he was attending Black Magic ceremonies, but during them he had also several times mentioned an Indian. They knew Morden to have been a regular attendant at Mrs. Wardeel's as, too, was Ratnadatta; and Barney had established the fact that the Indian was a link between her Theosophist circle and the Satanist circle at Cremorne, so it now seemed as good as certain that Ratnadatta had taken Morden there. But why should the Satanists have murdered him? His mission had had nothing to do with occultism of any kind. It had been the very down-to-earth business of finding out the ramifications of the Communist campaign to sabotage British industry. Yet it must have been something to do with that which had led him to Mrs. Wardeel's and to cultivate Ratnadatta; and, later, the discovery of what Morden was up to that had led to his death.

If that was so, it followed that Lothar was not making use of the house at Cremorne just because he had the entrée to it as a Satanist; it must be because the Satanic circle there was hand-in-glove with the Communists.

To have reached this conclusion was most satisfactory to C.B. and Barney, as they felt that it gave them an excellent chance of killing two evil birds with one stone. But the problem remained of how best to arrange matters so as to get the maximum number of this devilish crew in the bag at one fell swoop.

Apparently Lothar came to the house at Cremorne only on Saturdays, so to raid the place on any other day would leave him at large. It was, too, on Saturday nights that the Satanist circle gathered there, so there was good reason to believe that he came up from some hide-out on that day to be present at their weekly celebration. If, therefore, Special Branch surrounded the place the following evening and raided it about eleven o'clock, they should get him in the net with his associates.
