Nepenthe Gardens is the retirement home where Sally Jupiter lives in California. When the story opens, Sally is already a resident. Her daughter Laurie Juspeczyk visits there twice during during Eddie Blake's funeral services as she didn't want wish to attend. After she and Dan Dreiberg have assumed new identities (now calling themselves Sam and Sandra Hollis) they visit her on Christmas day.
Nepenthe is a drug bringing happiness and forgetfulness in some Greek legends.
