Hardly anyone attends St Martin's Church, Kengrave Square, in West London, and it's very nearly falling down. But when news gets out that it's to be closed, and possibly sold, there's a significant flurry of interest. The site is worth millions. Aziz Developments are after it, and so is the Community of Investors for Jesus - a curious American group of tele-evangelists. Enter the Honourable Mrs Monica Lodey, Kengrave Square resident, whose grandfather built the church. The venerable Mrs Lodey is determined to save St Martin's. She's not only rich but she can also exert huge influence: her brother is Chairman of Grenwood, Phipps, the merchant bankers, where Mark Treasure is Chief Executive.

When the vicar's wife launches a fund to repair St Martin's, there's a rowdy parish meeting where Treasure's actress wife Molly is the first to promise money. Treasure hopes that can be the extent of his involvement. But when a sudden death follows, spawning more dramatic events, both he and Molly find themselves gradually drawn into yet another investigation, and this time very close to home ground.
