He opened a steel gate, the bars of which were encased with thick layers of rubber, crossed a grassy plot (there were no stone-flagged paths at Norwood) and entered one of the three buildings which constituted the asylum proper. It was a harrowing, heart-breaking, and to some extent, a disappointing experience for Mr. Briggerland. True, his heart did not break, because it was made of infrangible material, and his disappointment was counter-balanced by a certain vague relief. At the end of two hours' inspection they were standing out on the big playing fields, watching the less violent of the patients wandering aimlessly about. Except one, they were unattended by keepers, but in the case of this one man, two stalwart uniformed men walked on either side of him. "Who is he?" asked Briggerland. "That is rather a sad case," said the alienist cheerfully. He had pointed out many "sad cases" in the same bright manner. "He's a doctor and a genuine homicide. Luckily they detected him before he did any mischief or he would have been in Broadmoor." "Aren't you ever afraid of these men escaping?" asked Mr. Briggerland. "You asked that before," said the doctor in surprise. "No. You see, an insane asylum is not like a prison; to make a good get-away from prison you have to have outside assistance. Nobody wants to help a lunatic escape, otherwise it would be easier than getting out of prison, because we have no patrols in the grounds, the wards can be opened from the outside without a key and the night patrol who visits the wards every half-hour has no time for any other observation. Would you like to talk to Dr. Thun?" Mr. Briggerland hesitated only for a second. "Yes," he said huskily. There was nothing in the appearance of the patient to suggest that he was in any way dangerous. A fair, bearded man, with pale blue eyes, he held out his hand impulsively to the visitor, and after a momentary hesitation, Mr. Briggerland took it and found his hand in a grip like a vice. The two attendants exchanged glances with the asylum doctor and strolled off. "I think you can talk to him without fear," said the doctor in a low voice, not so low, however, that the patient did not hear it, for he laughed. "Without fear, favour or prejudice, eh? Yes, that was how they swore the officers at my court martial." "The doctor was the general who was responsible for the losses at Caperetto," explained Dr. Carew. "That was where the Italians lost so heavily." Thun nodded. "Of course, I was perfectly innocent," he explained to Briggerland seriously, and taking the visitor's arm he strolled across the field, the doctor and the two attendants following at a distance. Mr. Briggerland breathed a little more quickly as he felt the strength of the patient's biceps. "My conviction," said Dr. Thun seriously, "was due to the fact that women were sitting on the court martial, which is, of course, against all regulations." "Certainly," murmured Mr. Briggerland.
