Dead Wood by Pandora Pine

After the harrowing events aboard the ghost train, Detective Ronan O’Mara is excited to reach the Double D Ranch in Deadwood, South Dakota. He plans to immerse himself in the old west by learning to ride horses, panning for gold and attending a rodeo. It’s the perfect mix of rest and relaxation he so desperately needs.
Psychic Tennyson Grimm also plans to take full advantage of this well-deserved downtime, but a visit to the famously haunted Bullock Hotel changes everything. Ten and Everly encounter a spirit desperately searching for her lost baby. When questioned, the woman can’t remember who she is, only that her missing daughter’s name is Madeline.
With the help of a local historian, Ten is able to determine the spirit is Grace Bailey, a southern debutante who’d fallen on hard times, dying in a brothel fire in 1894. When the ghost of Grace’s scoundrel husband appears, he has information that could solve the mystery of the fire and what happened to Madeline over a century ago, but the selfish man isn’t talking.

Who started the fire? Why? More importantly, what happened to baby Madeline?
