in the middle of the room.â
âYeah. Itâs weird but really relaxing. Thatâs the most comfortable chair Iâve ever sat in. Itâs got dozens of different positions. I sit in the chair, get comfortable, put on headphonesâand listen to music.â Dave shrugged. âThatâs all for the whole hour. Dr. Edberg said that there are subliminal messages on the tapes, telling us how to be better students, but I never heard them.â
âThatâs because you only hear them subconsciously,â Nancy said. âDid it help?â
Dave shrugged again. âI guess so. My gradeshave started to go up and not just in psych. Itâs as if Iâm listening better in all my classes.â
âCouldnât that just be because youâre spending extra time studying?â Bess asked.
âMaybe,â Dave said. âI guess I never thought of that. Edberg did say that some students might get a tape with no subliminal messageâso he could measure whether people who heard the message actually did better in school than people who didnât.â
Nancy tried to turn the conversation to Wayneâs murder. âAbout last night,â she began. âDid you see Parker?â
âNo,â Dave replied. âHe was supposed to come in at the end of my session, but he never showed. Edberg was really ticked off. He wanted to throw Parker out of the group, but Wayne wanted to give him another chance. I said he might be in the student union, since thatâs where everyone hangs out. So Wayne went to look for him.â
âWhat about Dr. Edberg?â Nancy asked.
âWe walked out together,â Dave told her. âI think we were the last people in the building. We said good night in the parking lot. Then he got into his car and drove away. I walked around a little, then came back to the house.â
So far, Dave wasnât giving Nancy anything new to go on. âThink carefully, Dave. Did you see anyone else at all in or around the building?â
Dave wrinkled his brow and clasped his hands behind his head. Then his eyes lit up. âCome tothink of it, there was someone. He was going in as we were leaving!â
âWho was it?â Ned asked urgently.
âJust some bald middle-aged guy in an overcoat. I never saw him beforeâfigured he was a professor,â Dave answered.
âIâm sure that some of the professors fit that description,â Ned said thoughtfully. âMaybe we should look through the faculty photos in a yearbook.â
âDr. Cohen is balding,â Bess put in.
âYou mean from the infirmary?â Dave asked. âHe does the team physicals. It wasnât him.â
Bess frowned. âI wonder who it was, then?â she asked. âI mean, if he was still in the building, he could be a witness!â
âOr a killerâdonât rule that out,â Nancy added grimly. âDave, keep an eye out for that man, okay?â
Dave promised he would, then got up to go. âI donât want to be late for class,â he said. He was heading for the closet when Nancy stopped him.
âOh, Dave. You said there were three girls in the group.â
âYeah, pretty ones, too,â he replied, grinning. âOne of them isnât on campus right nowâher father died. The other two are roommates, Janis Seymour and Diana DeMarco. They live over in Packard.â
âThatâs where weâre staying,â Bess said.
âDiana DeMarco,â Nancy repeated, searching her memory. âWasnât she the girl who stoppedWayne in the student union last night?â she asked Ned.
Ned snapped his fingers. âThatâs right! She seemed pretty angry with him, too.â
âI think weâd better talk to Janis and Diana next,â Nancy declared.

âI hope theyâre here,â Bess said later that morning. She and Nancy were standing in the
