"All right," said Ledsom, changing tactics. "If you had a deal in prospect with Schultz-Masters why didn't you go there until today?"
Harper gave a resigned sigh and said, "First, because my appointment was for today, not for yesterday. Secondly, I reached Hainesboro too late for any business calls—in fact, it was already too late when I left here."
"That's what interests us," informed Ledsom, gazing at him steadily. "You'd been badly delayed by the time we finished with you. All the same, you took time off to hunt up four people in a Thunderbug. Why did you do that?"
"Alderson died in my arms; I didn't like it."
Ledsom winced. "Is that your only reason?"
"It's the major one."
"What's the minor one?"
"My day was messed up. A couple of hours one way or the other couldn't make any difference.
"
"
No other motives whatsoever?
"
"
One," admitted Harper.
"Name it."
"I got some personal satisfaction out of finding a trace on the killers myself."
"If
they
were
the killers," commented Ledsom. He switched off the recorder, meditated a minute, and continued, "Up to a couple of hours ago I didn't doubt it; now I'm not so sure." He
kept his full attention on his listener, watching for reactions. "We're pumping out that pond. Maybe we
'
ll find the gun and lea
rn
who used it."
"Meaning me?"
"I haven't said so."
"You're hinting at it with every muscle in your face." Harper made a gesture of disparagement. "I can't blame you in the least for suspecting anyone and everyone. I
could
have killed Alderson; the time, the place and the opportunity all fit in. The only things lacking are the gun and the motive. You're going to have a hell of a time tying a motive onto me. I had never seen Alderson in my life until that moment."
"We had a senseless killing near here four years ago," answered Ledsom. "Two brothers fell out over an incredibly trivial matter. Finally the hotter-tempered of the two killed the other, and made a very clever try at concealing his guilt by distracting attention elsewhere. He
almost
succeeded."
"So I followed Alderson into a lane, stopped behind him, swapped backchat. One word led to another. Being cracked, I shot him twice, threw the gun into a pond and called you to come take a look." Harper pulled a wry face. "Time I had my head examined."
"I can't afford to overlook any possibilities," Ledsom gave back. "I've just asked you a lot of questions. Are you willing to take them again with a
li
e-detector?"
"Positively not
!"
Ledsom breathed deeply and said, "You realize that we must attach
a certain
significance to your refusal?"
"You can tie a couple of tin cans onto it for all I care. The polygraph is an outrageous piece of pseudo-scientific bunkum and its needle-wagglings aren't admissible as legal evidence."
"It has helped extract a few confessions."
"Yes, from the babes and sucklings. I am a maker of top-grade scientific
instruments
myself. You drag a polygraph into court and I'll tear it to pieces for all time."
That worried Ledsom. His thoughts revealed that he believed Harper perfectly capable of it.
"How about scopolamine?" suggested Harper, for good
measure.
"I'll talk that right out of usage if you'll give me half a chance." He leaned forward, knowing that their respective positions were reversed, even if but momentarily. "From the criminal viewpoint, what have I got that those punks in the Thunderbug haven't got? Do you regard them as figments of my imagination and think I've bribed witnesses to support my story?"
"They were real enough. We have proof of that."
"Well, then?"
"Two hours ago we picked up the girl. Her story doesn't jibe with yours; somebody's a liar."
Leaning back in his seat, Harper eyed him meditatively. "So you've got the girl. Is her version a trade secret?"
Ledsom thought it over and decided that there was nothing to lose. "She missed her bus, thumbed a lift. Three fellows picked her up in that green Thunderbug. They were in a humorous mood, took her a long, roundabout way and kidded her she was being kidnaped. At the filling station she really was scared; but after a bit more fooling around, they dumped her where she wanted to go. It was all a rib."
"And what about Alderson?"
"She saw nothing of him, knows nothing about him.
"
"
But he chased that car."
"I know. The girl says the blond fellow drove like a maniac, for no reason other than the hell of it, so maybe Alderson never caught up with them."
"You believe that yarn?"
"I don't believe
any
story without satisfactory evidence in support. But hers casts grave doubt upon yours."
"All right.
I know you're going to check on mine. Check on hers, too, and see if it stands up."
"We've already made a partial check on both of you, and we're going to finish the job as soon as possible. The girl doesn't know the names of the three fellows or anything else about them that we hadn't already found out. She didn't notice the number of the car. Having suffered nothing, she had no reason to grab the number."
"That's a big help."
"But the rest looks convincing," said Ledsom. "She is a girl of excellent reputation, coming from a highly respected family. She left home when she says she did, missed the bus she says she missed and was seen by two witnesses being offered a lift. She arrived at her destination at the time she states, and can prove it."
"Those fellows took her a long way round?"
"Yes. They were feeling their oats."
"Nice way of accounting for lost time, such as that involved in stopping, shooting, starting and getting away."
"Look, Mr. Harper, it's almost twenty-four hours since Alderson was shot down. All we've got are you and this girl; all I know is that somebody used a gun and somebody's telling lies."
"If that girl is telling the truth, which I beg leave to doubt," ventured Harper, "there's only one solution. A third party is wandering loose, untraced, unsuspected and laughing up his sleeve."
"There's not the slightest evidence of it." Ledsom hesitated, then went on, "I wouldn' dream of chewing the fat with you in this manner if it wasn't that your home town law gave you a very big hand. That sort of thing counts with me."
"I suppose so."
'Therefore, I'll tell you something more. The three fellows don't tally with any trio released or escaped from prison this year."
"How about the military prisons?
That old bird at the filling station thought they might be wearing altered uniforms."
"There is no military, naval or airforce uniform corresponding with that description."
"Not in this country. Maybe they were foreigners."
"The girl says not. They spoke the language as only we can speak it and knew the country like the backs of their hands."
"Have you asked the authorities whether they know of
any
uniform that does correspond?"
"No. The girl agrees that their clothes had a sort of official look, and thinks they were wearing army disposal stuff dyed green. If so, we've poor chance of tracing it. Ex-army jackets have been thrown on the market by the thousands."
"How about their car?
You thought it might be stolen."
"To date, we've pulled in reports of ten missing in various parts of the country. Four of them are green. We have urgent calls out for those four numbers; no luck so far." He gazed morbidly through an adjacent window. "Anyway, they may have resprayed it and changed the
tags. Or it may be legitimately owned. Or it may be a rented car. The Thunderbug is a popular make; it would take months to check all sales and rentals from coast to coast."
Harper thought it over and said, "Well, you'll know it if ever you lay hands on it. You have a tire-cast, and that's something."
"Doesn't follow it's one of theirs. Anybody could have gone up that lane anytime the same day. All we've discovered is that it doesn't belong to any logging vehicle. Neither do those three fellows answer the descriptions of any logging company's employees, past or present."
"No matter what that girl says, I still think they're the boys you want."
"The girl was an unwilling witness in that event. She wasn't a guilty party, so why should she cover up for a bunch of strangers?"
"Maybe they weren't strangers," Harper offered.
"What d'you mean?"
"It doesn't follow that because they gave her a lift they must have been unknown to her."
"She swears she didn't know them from Adam."
"You could bet on her saying that—if one of them happened to be a crazy boy friend, or a shiftless relative."
"H'm
!"
Ledsom viewed this as remotely possible, but rather unlikely.
"If she's telling lies about a murder, she must have a very str
ong reason. Perhaps she's been in
timidated."
"Wrong guess," snapped Ledsom, positively. "I've been in this game a long time and I can tell when a suspect is secretly afraid."
"I'm a suspect, too—a bigger and better one, to judge by what's happening right now. Think I'm scared?"
