The day after I speak to Costa, I receive a text from HTB’s genial head of PR, Mark Elsdon-Dew, suggesting I contact an HTB regular, Gary Flynn, to get another side of the story. I call Gary late on a Saturday evening. He has a rolling Cockney brogue and speaks with engaging fluency about the role that the church has played in rescuing him from the edge of despair — ‘God’s been brilliant,’ he says at one point. Until he came to HTB, Gary’s life lurched from tragedy to tragedy. His father was killed by a stray bullet at Deepcut Army Barracks, his brother died not long afterwards. Gary attempted suicide, taking an overdose aged 18. He lost a child to cot death. There were problems with drugs: ‘Every pint would be followed by a line,’ he told me. He buried himself in his work, setting up a scaffolding firm, and moved into a £1 million house with a swimming pool. Then, in his early forties, he was told he had bowel cancer. His business collapsed, he lost his home and moved into a caravan.
