Uncle Len is Elma Coogan's brother and Danny Coogan and Don Coogan's uncle. He is a carpenter for the Bodega Bay Inn during World War II and worked there restoring furniture. He had Danny to help him build chairs for a wedding reception in the hotel basement. He was also an acquaintance of Andre Toulon who had been staying at the hotel during this time. Danny had tried to convince his uncle about Toulon's stories of fighting Major Kraus and the living puppets, but he had just assumed those were tales fabricated by a senile old man.
