“But for your interest and consequent trespass,” Hamel remarked, “I should probably have found the roof off and the whole place in ruins.”

“Instead of which you found the door locked against you,” Mr. Fentolin pointed out. “Well, we shall see. I might, at any rate, have lost the opportunity of entertaining you here this evening. I am particularly glad to have an opportunity of making you known to my niece and nephew. I think you will agree with me that here are two young people who are highly to be commended. I cannot offer them a cheerful life here. There is little society, no gaiety, no sort of excitement. Yet they never leave me. They seem to have no other interest in life but to be always at my beck and call. A case, Mr. Hamel, of really touching devotion. If anything could reconcile me to my miserable condition, it would be the kindness and consideration of those by whom I am surrounded.”

Hamel murmured a few words of cordial agreement. Yet he found himself, in a sense, embarrassed. Gerald was looking down upon his plate and his face was hidden. Esther’s features had suddenly become stony and expressionless. Hamel felt instinctively that something was wrong.

“There are compensations,” Mr. Fentolin continued, with the air of one enjoying speech, “which find their way into even the gloomiest of lives. As I lie on my back, hour after hour, I feel all the more conscious of this. The world is a school of compensations, Mr. Hamel. The interests—the mental interests, I mean—of unfortunate people like myself, come to possess in time a peculiar significance and to yield a peculiar pleasure. I have hobbies, Mr. Hamel. I frankly admit it. Without my hobbies, I shudder to think what might become of me. I might become a selfish, cruel, misanthropical person. Hobbies are indeed a great thing.”

The brother and sister sat still in stony silence. Hamel, looking across the little table with its glittering load of cut glass and silver and scarlet flowers, caught something in Esther’s eyes, so rarely expressive of any emotion whatever, which puzzled him. He looked swiftly back at his host. Mr. Fentolin’s face, at that moment, was like a beautiful cameo. His expression was one of gentle benevolence.

“Let me be quite frank with you,” Mr. Fentolin murmured. “My occupation of the Tower is one of these hobbies. I love to sit there within a few yards of the sea and watch the tide come in. I catch something of the spirit, I think, which caught your father, Mr. Hamel, and kept him a prisoner here. In my small way I, too, paint while I am down there, paint and dream. These things may not appeal to you, but you must remember that there are few things left to me in life, and that those, therefore, which I can make use of, are dear to me. Gerald, you are silent to-night. How is it that you say nothing?”

“I am tired, sir,” the boy answered quietly.

Mr. Fentolin nodded gravely.

“It is inexcusable of me,” he declared smoothly, “to have forgotten even for a moment. My nephew, Mr. Hamel,” he went on, “had quite an exciting experience last night—or rather a series of experiences. He was first of all in a railway accident, and then, for the sake of a poor fellow who was with him and who was badly hurt, he motored back here in the grey hours of the morning and ran, they tell me, considerable risk of being drowned on the marshes. A very wonderful and praiseworthy adventure, I consider it. I trust that our friend up-stairs, when he recovers, will be properly grateful.”

Gerald rose to his feet precipitately. The service of dinner was almost concluded, and he muttered something which sounded like an excuse. Mr. Fentolin, however, stretched out his hand and motioned him to resume his seat.
