The Body in the Boudoir (Faith Fairchild #20) by Katherine Hall Page.*
Faith's own father is a minister, and when they were quite young, Faith and her sister had made a pact that neither would marry a clergyman. But that fantastic first date with Tom, and then cards, flowers and daily phone calls convince Faith rather quickly that she'll have to break that bargain because she's desperately in love with him.
Of course, since Faith Sibley is involved, there are always conplications. Her favorite Uncle Schuyler, who owns a mansion on Long Island offers to host the ceremony and reception, but when Faith and her mother go to meet the caterer there, they find a blood-covered body in his wife's bedroom. This does put a damper on things, but Schuyler insists the wedding must go on as planned. Faith agrees, but during the few weeks remaining, she does her best to figure out what happened.
The story will make sense to newbies, but will be much richer for those who've read some or all of the previous titles in the series. Page's prose is charming and the plot is aborbing. Prepare to read in one sitting!
