"Good old Nicky," he said. "Doing his bit!"

In those three days John went about with an air of agreeable excitement. Or you came upon him sitting in solitary places like the dining-room, lost in happy thought. Michael said of him that he was unctuous. He exuded a secret joy and satisfaction. John had acquired a sudden remarkable maturity. He shone on each member of his family with benevolence and affection, as if he were its protector and consoler, and about to confer on it some tremendous benefit.

"Look at Don-Don," Michael said. "The bloodthirsty little brute. He's positively enjoying the War."

"You might leave me alone," said Don-Don. "I shan't have it to enjoy for long."

He was one of those who believed that the War would be over in four months.

Michael, pledged to secrecy, came and looked at the Moving Fortress. He was interested and intelligent; he admired that efficiency of Nicky's that was so unlike his own.

Yet, he wondered, after all, was it so unlike? He, too, was aiming at an art as clean and hard and powerful as Nicky's, as naked of all blazonry and decoration, an art which would attain its objective by the simplest, most perfect adjustment of means to ends.

And Anthony was proud of that hidden wonder locked behind the door of the workshop in the orchard. He realized that his son Nicholas had taken part in a great and important thing. He was prouder of Nicholas than he had been of Michael.

And Michael knew it.

Nicky's brains could be used for the service of his country.
