"Shouldn't young Harris also be here?" Simpson asked, refolding his handkerchief.
"Or is Leyden 's primitive still hiding in the jungle?" sneered Vance.
Jake Saxer laughed nervously, then smoothed his yellow beard in embarrassment.
"We've spoken to him, and he had nothing of value to add to this inquiry," Sigrid said calmly in her school-marm manner. "For the record I'd like to hear your opinions on whether it would have made a difference if Professor Nauman had got the cup with potassium dichromate instead of Professor Quinn."
"It might to Oscar," suggested Leyden. Nauman shrugged; everyone else looked blank.
"I think she means cui bono?" said Simpson. "Who profits by his death?"
"Correct," said Sigrid. "Well, let's start with what happens now that Quinn's dead. You, Professor Simpson, will become deputy chairman, which means promotion and a larger salary?"
"If the majority of the department approve. I am senior historian."
"Do you need the extra money, Professor?"
"I have no family and my wants are few, Lieutenant, but you may examine my bank records if you feel it necessary."
"A full professor gets a bigger pension," Vance observed from his chair near the bookcase.
"So he does," Simpson agreed equably. "I hadn't thought of that."
"Of course, there are other rewards," said Sigrid turning to Jake Saxer. "How much is it worth to be listed as coauthor of an authoritative book rather than an insignificant contributor acknowledged briefly in the preface?"
The historian's pale face flushed. "I earned it! I've done ninety per cent of the work for that book. He promised me co-authorship before we ever began work!"
"Did you get it in writing?" asked Andrea Ross. "Riley Quinn wouldn't have shared authorship of a grocery list."
"Frigid bitch! You're just jealous because he passed you over."
"Surely you could invent a more crushing line, Jake," Professor Ross smiled icily. With her crisp curls and feminine clothes she looked like a porcelain doll; but beneath her artful makeup her face was pale. "You may have done ninety per cent, but that's just the donkey-work. Much as I despised Quinn, I have to admit he was a brilliant historian. His ten per cent will bring it all together, make the book a success. Maybe you can stick your name on his work, but none of his brilliance will rub off on you. My advice is to enjoy it while it lasts. Just don't try to write another book all by yourself, Jake, or Lieutenant Harald might have to arrest you for indecent mental exposure!"
Saxer sprang to his feet and for a moment actually seemed about to slap her, but Nauman grabbed his wrist with an unexpectedly strong grip and straight-armed him back into his chair with an ease that belied the force he had used.
"Andrea's right, so just sit down and stop being tiresome," he said. "Continue, Lieutenant."
Their eyes locked, then Sigrid referred to her notes again. "Professor Leyden, I understand that Quinn had planned a thorough hatchet job on you. I believe he called your work the 'pap of Polaroid pop.'"
"Riley was incapable of appreciating neo-realism," Leyden said airily, "and he didn't like my friendship with his wife. We were the best of enemies. You know, I'll probably even miss him."
"So what he planned to write didn't bother you?"
"Don't be naive, Lieutenant-of course it did! The gallery-trotting, picture-buying public is smart enough to read but dumb enough to be influenced by self-proclaimed savants; so I'm very lucky that Doris Quinn is going to accidentally burn some of his notes to that particular chapter."
There was a wicked gleam in Leyden 's dark eyes, and Nauman shook his head at the artist's audacity. "So now you'll get to dictate your own version, and Doris 'll get the pleasure of your company until the book's safely published."
Except for Detective Tildon everyone in the room knew Doris Quinn, and an undercurrent of ribald laughter swirled through the office.
"Just don't burn yourself out." Vance cautioned.
Sigrid looked at Andrea Ross. "With Quinn dead and Professor Simpson promoted, there's another associate professorship available now?"
Andrea Ross carefully tapped her cigarette ash into her empty cup and nodded.
"And you've admitted bitterness at being passed over the first time?"
Again the woman nodded, and Vance said, "Better remember that, Oscar."
Sigrid rounded on him sharply, "You keep acting as if this were all a big joke, Professor Vance. You were in and out of this office all morning, and you were here just before Professor Quinn picked up his cup and took it inside with him."
"And where's my motive?" taunted the stocky printmaker. "I wasn't in his book, I'm not sleeping with his wife, and he didn't cut me out of a promotion!"
"But if the poison had been meant for Professor Nauman?" she asked softly. "It's my understanding that if the chairman's an artist, the deputy must be a historian and vice versa. If Professor Nauman had taken that cup, Riley Quinn would have become chairman. So who's the artist who would get promoted to full professorship and be made deputy chairman?"
"Now just a minute," cried Vance. "No offense Oscar, but if I'd meant to kill you, you'd be dead now-not Riley. Besides," he said to Sigrid, "I'm no shoo-in. There're at least ten members of this department who hate my guts, and who would enjoy voting against me."
He said this proudly, and Sigrid noted wryly that he seemed to rate his standing as an artist by the number and caliber of his enemies.
"If the poison was for Oscar, that lets Saxer and me both out," said Leyden thoughtfully.
Professor Simpson cleared his throat. "Also me, I presume?"
"And you, Professor Ross?" asked Sigrid.
"If you think promotion's a strong enough motive for murder, then I'm still in. Either way an associate professor gets promoted to full, and I'm next in line for the associate."
The medievalist leaned back in her chair and lit another of the cigarettes she'd been chain-smoking all morning. Her brittleness had become even more apparent as the net tightened.
"We're like the Mad Hatter's tea party, aren't we Lieutenant? 'Move down! Move down!' Only there's an extra chair left over at this party and I'm not the only one who benefits either way, am I?"
Piers Leyden had been puzzled by David Wade's presence, and now he beamed appreciatively. "Why, Andrea, how very perceptive of you!" And he too, turned to stare at the young lecturer.
David returned their stares in bewilderment. "I don't understand. What's it all got to do with me?"
"Nothing!" cried Sandy, crumpling her empty cup in agitated hands. "He wasn't even here. He was in the library."
"That's true," Sigrid said. "We even have a student aide and a librarian from the reserve stacks who'll swear to it. But you were here, Miss Keppler."
" Sandy?" said Wade incredulously. "You've got to be spaced out. She's the last person in the whole department! Didn't you know? We're getting married this summer. Probably move to Idaho."
"Why?"
"Because my contract's expired and-oh."
He looked like a man who'd been kicked in the groin, and his eyes sick as he spoke to Andrea Ross. "That's what you meant about an extra chair left over."
"I'm afraid so," said Sigrid. "Your contract expires in June. They couldn't extend it without offering you tenure, and until Wednesday there wasn't a tenured position open. Now there is. After Professors Simpson and Ross are promoted, there'll be an unfilled position left on the history side. Either way Wade would get tenure, wouldn't he, Professor Nauman?"
Nauman nodded stonily. "A chairman teaches only one course. Riley dead or promoted to chairman-either way-someone would have to take up the slack of his other classes. I was going to speak to David this afternoon. Discuss tenure."
