His meaning was clear enough, and a shudder ran through C. B. at the thought that his blood was to be used to sustain the life of those foul creatures in the jars.
`A pint is the usual quantity given by blood donors,' the Canon went on thoughtfully, `but that hardly affects them; so I shall take from you at least a quart. Such a drain on your vitality will more than double the effect of the drug; so for a quarter of an hour or more you will be too weak to lift a finger. And to render you incapable of all movement for ten minutes will be ample for our purpose.'
C.B.’s strength was now fast returning to him. He could move his toes, clench his fingers, and flex the muscles of his arms and legs. Temporarily giving way to the fear that was upon him, he began to shout curses at the Canon and strive violently to free himself. His struggles were in vain; the string cut into his wrists and ankles, but his efforts failed even to loosen it materially.
With a contemptuous smile, the Canon watched his abortive squirming for a few moments; then he said, `Directly I learned that you were an impostor I hurried back here, in case you took it into your head to harm the homunculi during my absence; so I have yet to hear the full report of de Grasse's messenger. It would be a great mistake to put you on the line unnecessarily early, in case
someone stumbled on you. I am, therefore, about to fill in ten minutes by listening to what else the messenger has to say, and putting in a personal call to de Grasse for midnight, so that I may give him fresh instructions. When I return I shall give you your second dose of the drink you found so palatable. They say that when near death one recalls one's childhood. My having to hold your nose while you take your medicine should help you to remember similar episodes when in your nursery. We shall then perform the little operation by which you will donate your blood to such an admirable cause. That should take us up to about five minutes to eleven In the meantime my man, Achmet, will have brought the wheelbarrow round from the gardener's shed. The margin of ten minutes I have left should be just right for me to give you your final dose, and have you transported to the scene of your execution.'
Turning on his heel he walked sedately the length of the crypt with his hands clasped behind his back. As he switched out all the lights except two and left it, locking the door after him, C. B. watched him go with a feeling of sick despair. There seemed such an air of terrible finality about the Satanist's present calmness. That he was apt to fly into rages was evident from the intense anger he had shown at the suggestion that his sanctuary might be invaded; but there was something infinitely more menacing in his general behaviour since he had discovered that C. B. was an impostor. Swiftly, yet carefully, he had made his arrangements to commit a cold blooded murder, and had discussed it in detail with such unruffled composure that it looked as if nothing short of a miracle could prevent his going through with it.
A cold perspiration broke out on C.B.’s forehead as he thought how slender were the chances of such a miracle occurring. He had already dismissed the idea that he might be rescued by John as in the highest degree unlikely. He had told John that if he was not out of the house by midnight he was to telephone the police and come in to find him. But by midnight, if the train was punctual, he would have been dead for fifty five minutes; and John would certainly not attempt to force his way in more than an hour before the time he had been given. For all he knew, matters were going excellently and, as the Canon was certain to recognise him as Ellen's friend, his premature entry, seeking C. B., might have thrown a spanner in the works at their most promising point. Besides, there was no earthly reason why he should ignore his instructions and risk upsetting everything, unless ...
C. B. stiffened in his chair . . . unless John had seen the messenger arrive and recognised him as one of de Grasse's people. If that happened he would know that the odds were on C. B. being caught out. Then, if C. B. did not appear within quite a short while, there would be grounds for assuming that he was in trouble. What would John do in such circumstances? If he enquired at the front door he would be told that C. B. had already left by the back entrance and was taking the short cut to the village. He would not believe that, but he might decide to return to the village to make certain. In any case he would do so, to telephone the police before taking further action. Then what? John would come back and endeavour to get into the house. If he succeeded, and was discovered, he would be one against three. Even if he managed to get in undetected he would not know where to look for C. B. The windows of the crypt had all been bricked up, so there was no chance of his entering it direct from outside; and he could not possibly force its iron door. Only one slender chance remained: he might come upon the Satanists when they were carrying their victim out into the garden.
With frantic anxiety C. B. began to calculate times. De Grasse's messenger had arrived just before half past ten. John would wait at least ten minutes to see if C. B. came out of his own accord, before taking any action. To enquire at the front door would take him from three to five minutes, and it was a good ten minutes' walk to the village. There might be a public call box on the green, but never having been in the place before John would not know where to find it, and the odds were all against his running into it in the darkness. He would have to telephone from the pub, but that would now be closed. To knock it up and get on to Colchester would take him another ten minutes; then he would require ten more minutes to walk back to the house. There was the possibility that he would take the car both ways, but on such a short distance the best to be hoped for from that was that it would reduce the total time from forty five to thirty five minutes. Therefore, at the earliest reasonable moment that John could be expected to begin reconnoitering the house for the easiest place to break into it, the London train would be thundering over C.B.’s body; and even that was on the assumption that he had seen de Grasse's messenger, recognised him, and decided to take prompt action.
At the conclusion of his calculations C. B. let go a gasp rather than a sigh. It was no good. He was caught without hope of rescue. His number was up, and he must face it. He had barely a quarter of an hour of life left.
Fruitlessly, he cursed himself for his foolhardiness in having walked into such danger on an impulse, and without making provision for an adequate life line. He felt that he, of all people, had had experience enough to know better. Yet, on consideration, had he really been so very rash? At worst there had been no reason to anticipate anything more serious than that the Canon might find him out and have him beaten up, then locked in the cellar or attic till the morning. Had he speculated for a week on the possible outcome of such a visit, it would still not have occurred to him that by making it he might lose his life. Neither would there have been the least likelihood of his doing so, had not the success of his imposture led to his being taken into the Canon's confidence so unreservedly and shown things, the existence of which he had not even remotely suspected.
It was his having learned about the homunculi that put the rope around his neck, and it was that which made it futile to hope that Copely Syle was seeking only to frighten him. Having given away his awful secret, no oaths or pledges that the Canon could extract from his prisoner would satisfy him that he might not now be called on to account for his hideous practices. Should he once release C. B. he would lose all power to enforce his silence, whereas in this next half hour he had the chance to close his mouth once and for all. It was this final realisation that the Canon had no option but to kill him that made C.B.’s heart contract with despair and his face sweat with terror.
Yet he was not the man to give in until the last ditch.
