He tossed the bit of paper to Rex and fell back in his chair overcome by something very like fear.

Rex glanced at the despatch and then returned to the study of his figure without betraying any surprise.


CHAPTER VIII

Greif’s first sensation was that of astonishment, almost amounting to stupefaction. Rex could have desired no more striking fulfilment of a prediction than chance had vouchsafed to him in the present instance. For he admitted to himself that fortune had favoured him, even though the arrival of the news within twenty-four hours was not in his belief a mere coincidence. The telegram might have come at any other moment and might have found Greif in any other place. As for Greif, he saw at a glance how impossible it was that Rex should have foreseen the incident, or planned the circumstances in which it occurred. He could not have known that Greif was coming that evening, unless he knew everything, and moreover the despatch was fresh from the office, and twenty minutes had not elapsed between the time of its reception over the wires and of its delivery into Greif’s hands.

If the occurrence was strange, its effect upon the young man was at least equally unforeseen. Greif had always despised persons who professed to dabble in the supernatural, and had laughed to scorn all the so-called manifestations of spiritualism, mesmerism, and super-rational force. When he had heard that the great astronomer Zollner had written a book to explain the performances of Slade, the medium, by means of a mathematical theory of a fourth dimension in space, Greif had believed that the scientist was raving mad. Up to the moment when the telegram had arrived, he had been convinced that Rex was a cheat, who had accidentally learned certain facts connected with the Greifensteins and was attempting to play the magician by making an adroit use of what he knew. When brought suddenly face to face with a phenomenon he could not explain, Greif’s reason ceased altogether to perform its functions. The news he had just received was startling, but the bewilderment caused by its arrival at that precise juncture made even Rieseneck’s return seem insignificant, in comparison with Rex’s power to foretell the announcement of it.

‘I do not understand,’ said Greif, staring at his companion.

‘Nor I, beyond a certain point,’ replied the elder man, looking up from his paper.

‘How could you know?’
