The House of Spies by Warwick Deeping

Jasper Benham grew very restless those April days, though he moved in a cool, green world, and saw the primroses starring the banks of the paddock, and Squire Kit's Dutch tulips opening their cups of crimson and gold. The "cuckoo's mate" had come, and called plaintively in the oak-trees. The grass in the orchard was the colour of emeralds, and the fruit-buds were opening against the blue.

Jasper was restless, adventurous, obstinate, and Surgeon Doddington protested. He was a little, purplish man with a huge, bald head, who talked very fast and spluttered as he talked. A wag had once watched Surgeon Doddington with extreme attention for fully five minutes, and then explained that he had been waiting to see him blow up.
