Lost in the Light & Girl in the Mist by Mary Castillo

Detective Dori Orihuela has recovered from a bullet but the guilt remains. Haunted by her past, she's surprised when a move into a Victorian mansion fills her nightmares with more than her own demons. The ghost of a 1930s bootlegger wants answers, and the only way for Dori to exorcise her own conscience may require solving the mystery of the spirit's one true love.
