Lorenzo was waiting by the barn, his expression concerned. There wasn’t panic, so Caleb wasn’t too worried but he knew the vaquero was hard to ruffle.He stopped and dismounted, then yanked off his gloves. “What’s wrong?”Nick jumped down with a jingle of spurs. “What do you mean what’s wrong?”“Shut up a minute and let Lorenzo talk.” Caleb stepped toward the ranch hand, his worry growing.“Mariposa is gone.”“What do you mean, she’s gone? Did someone take Liv’s mare?” The theft of one of their best broodmares would put a dent in their plans to raise their own horses.“Sí, Olivia did.” Lorenzo shook his head. “She’s been gone since before dinner.”Caleb closed his eyes and counted to ten. “Do you know where she went?” His older sister wasn’t the type of female to take off on flights of fancy. She ran the ranch like a military camp and was more disciplined than anyone he knew. When Matt and Hannah were gone, Olivia took great pleasure in ordering everyone around.
