Nancy crossed to the supply room. Everything looked much as it had when she had seen it a couple of hours earlier. Then she noticed the hypodermic syringe and several vials of tranquilizer were missing.

            "Did anyone take a syringe and some tranquilizer vials out of here?" Nancy asked over her shoulder.

            Alicia stepped inside and checked the shelf.

            "Oh-they are missing. But who would have taken them?"

            Nancy's thoughts raced. First the group had discovered fifty marmots missing, and now someone seemed to have stolen tranquilizers that could sedate more marmots. Was someone planning to tranquilize the fifty stolen creatures so they could be quietly shipped out of the park?

            Before she could ask more questions, Nancy saw Professor Trainey at the doorway.

            "Now what?" he demanded, slightly out of breath. "Can't I leave this project for five minutes without-" His voice faded as he noticed Ned on the floor.

            "Someone hit Ned over the head," Jennifer told her father. "And tranquilizers are missing from the supply room."

            Trainey's eyes widened as he knelt beside Ned. "We've got to get you up to the hospital in Gardiner as soon as we can." He glanced around the room, clearly upset. "Can someone drive him there? We can't take chances-not with a head injury."

            "I'll go," Nancy quickly offered. "Where is it?"

            "Gardiner is just over the state line in Montana, right outside the north entrance of the park. I'll ride along and show you the way," Jack offered. "Just give me a couple of minutes to clear it with headquarters."

            Nancy remembered the object she had stashed in her pocket. She slipped it out unobtrusively. It was a Phi Beta Kappa key. Turning it over, she saw the initials D.T. engraved on the back. Dan Trainey.
