      “Where—?”

      “Family heirloom,” Jet said. “We’re the sentimental sort.”

      Shelly almost snickered. Jet and Lily didn’t have a sentimental bone or scale on their mermaid bodies. Unless you counted Jet’s unexplained preoccupation with Perry, her human lover and partner in shipwreck recovery crimes—who turned out to be a lying, self-serving scumbag, now serving time.

      And good riddance, Shelly and Lily told each other. Unfortunately, Jet was still hung up on the guy, even if she refused to admit it. She probably mistook him for a swashbuckling pirate, à la Johnny Depp.

      “Fascinating place you have here,” Tillman said, eyeing the large brass porthole above the fireplace. Shelly couldn’t help but feel a little surge of pride. That porthole had been a lucky discovery on her part when she was only sixteen years old and visiting the Bosarge family for the summer. She’d been swimming five miles from the house when her eyes picked up a reflective glint from a black sand bed. It had been a risky and difficult swim home with her prize, but she’d managed.
