Second Sight by Amanda Quick (aka Janye Ann Krentz)

Photographer Venetia Milton is a spinster by Victorian standards. Economically strapped, she's also the sole support of her aunt and younger siblings. Things start to look up when she is chosen to photograph a collection of artifacts belonging to the Arcane Society, a 200-year-old clandestine organization founded by an alchemist. The collection is housed in an isolated gothic mansion, and Venetia finds herself there in the company of handsome and mysterious Gabriel Jones. Deciding that it's now or never for love, Venetia seduces him, only to lose the man of her dreams in a fire set by a nefarious enemy.

Venetia resourcefully moves on, opening a portrait shop and assuming the persona of Gabriel's grieving widow. The talented Mrs. Jones becomes the toast of London, but with Gabriel soon showing up on her doorstep very much alive, Venetia adapts herself again. Now to the former widow reunited with her assumed dead husband. Miffed, she consigns him to the attic, but their chemistry quickly reignites; while tracking down one murderous, blackmailing thief after another, they steal opportunities for fervent encounters in the garden, in the carriage, in the society's mansion and at home.

I enjoy her books especially her more science fiction books she writes under Jayne Castle. But I enjoy reading any of her books she comes out with. She is a fun and easy read.
