Murder, She Wrote: Killing in a Koi Pond

After traveling to Bethesda for a mystery writers' conference, Jessica Fletcher decides she's earned a vacation and takes a train to Columbia, South Carolina, to visit her old college friend Dolores, who has recently married her third husband, Willis Nickens, a wealthy and cutthroat businessman. They've moved into an opulent historic home with plenty of space for guests, and Jessica is ready for a week of shopping, gossiping, and relaxing at the grand estate. But the morning after she arrives, Jessica discovers Willis facedown in the koi pond, and despite what the police think, she's sure foul play is involved. She hadn't known Willis long, but it's clear to her that he didn't concern himself with making friends. The question isn't if her friend's husband was murdered but by whom.
