One inoffensive drunkard. So many reasons to kill him.

A bold shooting ends the life of Mr. Hewitt, the buggy manufacturer on a cold night in December, 1872. Physician and winemaker Maddie Wilcox is particularly puzzled, since it was clear that Mr. Hewitt was soon to die of his own dissipation. Nonetheless, she is drawn into searching out his killer by the grieving widow.

Maddie soon finds out that there were several people who might have been offended by Mr. Hewitt, including those hoping to bring the Union Pacific railroad to Los Angeles. As Maddie battles the usual winter colds and her own homesickness, the local men begin vying for her affections. Soon, Maddie realizes that she is searching for a killer determined to win the prize, no matter what the cost.
