THE CASE OF THE CAMPUS KILLER

	     We've had other crimes committed at State," Dean 
	Davis told Detective Joe Harrell. "But not murder! Poor 
	old Cory..." 
	     Harrell said: "I gather your caretaker lived in 
	the supply building, since he was in his pajamas." 
	     "Yes--in a small apartment at the rear. Do you know 
	how he was killed?" 
	     "Looks like he was struck by a baseball bat. It may 
	have been replaced in the racks, or left outside when the 
	killer escaped." 
	     "And you're sure the motive was robbery?" 
	     "All the cash was gone from the register. And there 
	was sporting equipment all over the courtyard. Obviously, he 
	tried to steal them, too, but Cory interfered. I doubt 
	the robber meant to kill him, but that's what happened." 
	     The Dean groaned. "We've had other robberies. That's 
	why we built the Wall!" 
	     Harrell had seen the wall. It was thirteen feet high 
	and surrounded the long narrow building. It was topped with 
	barbed wire. 
	     "I know it's prison-like," the Dean said. "We're going 
	to plant rose bushes around it... But if Cory was killed 
	after dark, how did the murderer escape?" 
	      Harrell hesitated. "There is a gate--" 
	     "Padlocked at five o'clock, every night! It was still 
	padlocked this morning, when we found Cory's body. How did 
	he get away?" 
	     The Detective picked up the list the Dean had written. 
	     "You're sure these are all the students who entered the 
	building yesterday?" 
	     "Everyone has to sign their name at the entrance. But 
	they don't have to sign out." 
	     The Detective knew what he had to do next. The list of 
	names had to be shortened. 
	     It didn't prove difficult. Most students on the list were 
	in team athletics. Their presence on the playing fields were 
	confirmed by others. Harrell soon pared the list down to three. 
	    He went to the Admittance Office and asked for their files. 
	    Near Far seemed an unlikely thief. He was the son of 
	a man who owned the local car dealership. 
	    Near said. "I went to the supply room to buy some new 
	tennis balls. I left around four-thirty. And no-- I didn't 
	see either of the two guys you mentioned." 	
	     The Detective looked at the file. "I see you have a 
	few hobbies. Biking, tennis, mountain-climbing, auto racing..." 
	     Near remained silent. 
	     Tim Bryan was a lanky young man who answered 
	indifferently. "Yes, I was in the building, but I don't 
	remember seeing either Brita or Near. I checked out some 
	baseballs. I'm a pitcher, you know. That's how I got my 
	scholarship." 
	     Next was Brita Filter. She was bitter. 
	    "I pay my own way here-- no scholarship, no family money. 
	But that Near Far you mentioned-- he told me his parents 
	cut off his allowance a few months ago." 
	     "You're quite an athlete yourself." Harrell looked at 
	the folder. "Track and field?" 
	     "So that's it!" Brita said. "I heard that track and field 
	stuff was all over the courtyard! Somebody tried to make me 
	look guilty!" 
	      When he entered the Dean's office the next morning, the 
	Detective was downhearted. 
	     "All three students needed money," he said. "I'm sure 
	that's the motive. What I don't know is which one is guilty."
	"There's only one way to decide," the Dean said ruefully.
     	    "Find out which one can walk through walls!" 
	     Suddenly, Joe Harrell's eyes lit up like two sunrises. 
	    "You're right, Dean. And I know which student can do just 
	that!"
