Justin Quayle is a low-level British diplomat who has always gone about his work very quietly, not causing any problems. But after his radical wife Tessa is killed he becomes determined to find out why, thrusting himself into the middle of a very dangerous conspiracy.

A manager hires Ray, off the books, to paint all the power towers in a 15-mile stretch of high-tension wires outside Sheffield. Ray's crew of men are friends, especially Ray with Steve, a young Romeo. Into the mix comes Gerry, an Australian with a spirit of adventure and mountain climbing skills. She wants a job, and against the others' advice, who don't want a woman on the job, Ray hires her. Then she and Ray fall in love. He asks her to marry him, gives her a ring. Steve's jealous; Ray's ex-wife complains that he spends on Gerry, not his own kids, and she predicts that Gerry won't stay around. Plus, there's pressure to finish the job fast. Economics, romance, and wanderlust spark the end.
