To her infinite relief, Mr. Jardine appeared at this moment. He questioned Towler as to the possibility of tranquillising his patient; and he found that the sedatives prescribed by Dr. Mallison had ceased to exercise any beneficial effect. Nights of insomnia and restlessness had been the rule with the patient ever since Towler had been in attendance upon him. 'I never knew such a brain, or such invention!' exclaimed Towler; 'the people and the places, and the things he talks about is enough to make a man's hair stand on end.' 'The natural result of a vivid memory, and a good deal of desultory reading.' 'Most patients takes an idea and harps upon it,' said Towler. 'It's the multiplication table--or the day of judgment--or the volcanoes and hot-springs, and what-you-may-call-ems, in the centre of the earth; and they'll go on over and over again--always coming back to the same point, like a merry-go-round; but this one is quite different. There's no bounds to his delusions. We're at the North Pole one minute, and digging up diamonds in Africa the next.' Brian had flung himself upon his bed, rolled in the damask curtain, like Henry Plantagenet, what time he went off into one of his fury-fits about Thomas Becket; and Mr. Jardine and Towler were able to talk confidentially at a respectful distance. 'Are you sure that he does not get brandy without your knowledge?' 'No, sir,' said Towler; 'that is what I am not sure about. It's a puzzling case. He didn't ought to be so bad as he is after my care of him. There ought to be some improvement by this time; instead of which it's all the other way.' 'What precautions have you taken?' 'I've searched his rooms, and not a thing have I found stowed away anywhere. It isn't often that he's left to himself, for when I get my midday sleep Mrs. Wendover sits with him; or, if he's cranky, and wants to be alone, she stays in the next room, with the door ajar between them; and Robert, the groom, is on duty in the passage, in case the patient should get unmanageable.' 'I see--you have been very careful; but practically your patient has been often alone--the half-open door signifies nothing--he was unobserved, and free to do what he pleased all the same.' 'But he couldn't drink if there was no liquor within reach.' 'Was there none? that is the question!' answered Mr. Jardine. 'Look about the rooms yourself, sir, and see if he could hide anything, except in such places as I've overhauled every morning,' said Towler, with an offended air; and then, swelling with outraged dignity, he flung open doors of wardrobes and closets, pulled out drawers, and otherwise demonstrated the impossibility of anything remaining secret from his eagle eye. 'What about the next room?' asked Mr. Jardine, going into the adjoining room, which was Brian's study.
