"Yes, I do," answered Helling with some trepidation.

"Fifteen shillings," said Lincott. "Think of it, fifteen shillings, perhaps sixteen."

"I know," interrupted Helling quickly, mistaking the surgeon's meaning. "But please, please, you mustn't think I value what you have done for me at that. It's only fifteen shillings, but it has meant a fortune to me all the last three weeks. Each time that I've drawn my belt tighter I have felt that coin underneath it burn against my skin. When I passed a coffee-stall in the early morning and saw the steam and the cake I knew I could have bought up the whole stall if I chose. I could have had meals, and meals, and meals. I could have slept in beds under roofs. It's only fifteen shillings; nothing at all to you," and he looked round the consulting-room, with its pictures and electric lights, "but I want you to take it at what it has been worth to me ever since I came out of the hospital."

Lincott took Helling into his dining-room. On a pedestal stood a great silver vase, blazing its magnificence across the room.

"You see that?" he asked.

"Yes," said Helling.

"It was given to me by a patient. It must have cost at the least £500."

Helling tapped the vase with his knuckles.

"Yes, sir, that's a present," he said enviously. "That is a present."

Lincott laughed and threw up the window.
