Send a White Rose — Mary C. Findley

Shattered by and assassination attempt, Bart Durant's got no stomach to deal with a mail order mistake. While meeting New Mexico Territorial Judge Bartholomew Durant, Leah Masters steps into an assassination attempt, her brother's imprisonment for murder, resentment from a best friend with a cavalry sword, and a rival in the form of a beautiful and godly best friend. While cleaning house and keeping accounts she falls in love with a bitter, scornful suitor whose opinion she's too afraid to change.
