Léo stared. He looked at the rain dripping through a hole in his roof. Then at his car.

“The brown connector on the UCH module fails due to capillary action in rain. Do not replace the €900 harness. Cut pin 14. Solder a jumper wire to pin 7 of the wiper motor relay. Wrap in self-amalgamating tape. Cost: €0.30. The official fix is a lie.”

He never told the dealer how he fixed it. But every time a broke student showed up with a hopeless Renault, Léo would boot up the old PC, wipe the dust off the disc, and whisper: “Time to ask the ghost.”
