Just as the last of the yoga group left the room, Cathy came out and Jack Matherson appeared at the far end of the gym. He came over, carrying a briefcase that appeared quite heavy. “Good evening, Cathy, Dennis. Good to see you.” He winked at Dennis. “Would you care to join us?” “Oh, er, yes, OK. Thanks.” Dennis eased the weights down gently on his machine and followed Jack and Cathy to her office. Jack placed his briefcase on her desk and opened it. “Can you tell me if this looks like a piece of your equipment, Cathy?” He pulled out a black iron dumbbell enclosed in a plastic evidence bag and handed it to her. She looked up at him, startled. “Oh God, this isn’t the murder weapon, is it?” “We don’t know for sure just yet, but we found two of them with the body. We think they were used to hold it underwater. It would have worked, too, if that heavy rain hadn’t dragged the body away from the sheltering bank and moved it out into view.” She stared at the item, turning it over and peering through the bag.
