Crimson Mist - The Vincent Coronado Mysteries, #2

At long last, and from an unusual source, Vincent Coronado finally has a clue to the murder of his beloved wife Lori nearly a decade ago. But it appears that she had not been murdered in a botched ransom scheme, but in a far more horrifying manner, and for far more horrendous reasons. And it also appears that a great lot of people will have to die, if Vincent is to avenge his wife.
