Sometime in the early 2000s, in the Swiss alpine town of Thun, a woman went away to Cape Town for a few weeks. While she was gone, a friend house-sitting her flat opened a cupboard beside the boiler and found it scattered with cash. Thousands of Swiss francs, lying on the floor of the cleaning cupboard. Nobody could say where it had come from.

The woman was Susanna Rychiger. She had grown up in a Swiss business family. Her father ran a machinery factory, and she had walked away from all of it to do one thing: pray. In 1999 she helped start the 24-7 Prayer movement in Switzerland, a room in Thun where someone was praying around the clock, every hour of every day.

She believed God had told her to move into a flat in the centre of town, close to the people who needed help most. The rent was far beyond what she could afford. So she cut back on everything, and she held onto one line from Psalm 55: cast your cares on the Lord, and he will sustain you.

Then the money started to appear. Her friend Rebecca found that first scattered cash while Susanna was away. After she came home, it happened again. One day, around thirteen thousand six hundred francs lay on the floor of a closet. Another morning, two hundred francs sat on top of the boiler. The next morning, another two hundred.

Four separate times, in less than a month, money simply turned up. Roughly twenty-eight thousand Swiss francs in total. About a year's wages.

She checked. The bank reported that no one had lost it. The police said nothing had been stolen. That, at least, is what the account records.

Because this story has no laboratory, no medical file, no Church commission. Its source is one book: Dirty Glory, by Pete Greig, who tells it as the testimony of his friend. A house-sitter, a boiler cupboard, and a bank that says nobody is missing the money.

Susanna's own conclusion was simple. Either the world's most confused burglar broke in to leave thousands of francs and slip away without a trace. Or someone had heard her. She called it the cashpoint God installed in her kitchen. And she gave the rest away.
