He held his hand out for the bow and pointed to a little gate at the end of the path.

“There’s the gate into Hammer,” he said, and added with exquisite awkwardness, “I beg your pardon; I’m very poor company as you see. Thank you for bringing the stuff. Thank you, thank you.”

She gave him the bow and took charge of her bicycle. “Dr. Mark Lacklander may be very young,” she said bluffly, “but he’s as capable a G.P. as I’ve come across in thirty years’ nursing. If I were you, Commander, I’d have a good down-to-earth chinwag with him. Much obliged for the assistance. Good evening to you.”

She pushed her bicycle through the gate into the well-tended coppice belonging to Hammer Farm and along a path that ran between herbaceous borders. As she made her way towards the house, she heard behind her at Uplands the twang of a bowstring and the “tock” of an arrow in a target.

“Poor chap,” Nurse Kettle muttered, partly in a huff and partly compassionate. “Poor chap! Nothing to keep him out of mischief,” and with a sense of vague uneasiness she wheeled her bicycle in the direction of.the Cartarettes’ rose garden, where she could hear the snip of garden secateurs and a woman’s voice quietly singing.

“That’ll be either Mrs.” thought Nurse Kettle, “or the stepdaughter. Pretty tune.”

A man’s voice joined in, making a second part.

The words, thought Nurse Kettle, were a trifle morbid, but the general effect was nice. The rose garden was enclosed behind quickset hedges and hidden from her, but the path she had taken led into it, and she must continue if she was to reach the house. Her rubber-shod feet made little sound on the flagstones, and the bicycle discreetly clicked along beside her. She had an odd feeling that she was about to break in on a scene of exquisite intimacy. She approached a green, archway, and as she did so, the woman’s voice broke off from its song and said, “That’s my favourite of all.”
