Trout Walker
Trout Walker was a man living in Green Lake, Texas.
Green Lake
Trout was the son of the owner of the lake in Green Lake, Texas. He was a bigoted and self centered man. He thought the entire world was his. He was also a racist person. (this was expressed multiple times around Sam). Trout ended up marrying Linda Miller (she was one of Kate's former students.)
Katherine Barlow
Trout wanted to be involved with Katherine (Kate) Barlow. However, she told him that she had no interest in him. When Trout saw her kissing Sam, the dark-skinned onion farmer, he was infuriated. He personally shot Sam and Sam's donkey, Mary Lou.
After Lake Dried Up
After Sam was murdered, it never rained again and eventually the lake dried up. This caused Trout to lose all his money. When Kate Barlow returned to bury her loot, he threatened her to try to find her loot. However, Kate committed suicide by making a Yellow-Spotted lizard bite her. This made it impossible for Trout and his descendants to find the loot which made him go mad to let himself and his granddaughter, The Warden dig up holes everyday even on Christmas much to the warden's dismay.
