The Adept 1st in the Adept series by Katherine Kurtz and Deborah Turner Harris
Meet Adam Sinclair, a psychiatrist, a nobleman, a scholar, and "Master of the Hunt" who possesses intriguing "magical" powers along with the ability to recall past lives. With help from his friends Peregrine Lovat, the artist, and Noel McLeod, the detective, Adam embarks on a series of adventures in which he attempts to right situations involving historical items and to keep the dark from conquering his beloved Scotland and more.

An interesting series. Lots of things are introduced that will be interesting to see how it developes in the series. The ending definitely leaves sequels open.
