Detective Conan S01 E282 Mystery of the Water Flowing Stone Garden (1)

"One truth prevails."

Kogoro, Conan, and Ran are driving in the mountains when they run out of gas and are kindly picked up by Majima, the president of a furniture company. Most of the people that work for him and live with him seem to hate him, so it isn't a surprise when Majima turns up dead the next morning in the beautiful house rock garden.
