The Candlewick Inn Mystery — J.H. Sweet

Surely, it can't be possible to find two treasures in one summer. But that's exactly what Cassie and Enilsa are trying to do. While spending two weeks helping out at the Candlewick Inn, a property Cassie's cousin will soon inherit from their late Great-Aunt Sybil, the girls find several clues relating to something valuable hidden at the inn. While investigating, they receive messages from a psychic, and even a note from Great-Aunt Sybil herself, which help them solve The Candlewick Inn Mystery.
