This is book 2 in the Tipperary Carriage Company cozy mystery series by USA TODAY Bestselling Author J A Whiting and Nell McCarthy. Mae Monahan owns a horse-drawn carriage business and she has a new horse named Copper to work with. The reddish-brown horse with a long white mane and tail has a sweet personality, but he’s a skittish handful when he is in harness and Mae worries that Copper won’t be ready for the Valentine’s Day job she has planned. After taking a young couple out for a horse-drawn carriage ride and marriage proposal, Mae finds something under the floor mat in the carriage that alarms her and she turns to a police detective she knows for advice. One thing leads to another until Mae and her horse are drawn into a mystery of theft, deception, and worse. With the help of her friend, Ross, the stable owner and retired lawman from Texas, will Mae be able to keep the criminals from harming them and her horses? Will she be able to figure out the diamond deception before it’s too late?
