“I’m just trying to get at this,” said Bob. “Both of us have chances for brilliant futures in this service if we don’t let personal rivalry warp our better judgment. That was a shabby trick of yours in giving that story to the newspapers and I rather think you hoped that I would be blamed.”

Tully was silent and Bob went on.

“I’m willing to let that pass and some other things that have happened if you feel that you’re willing to work along with me on this case. The old saying that two heads are better than one is certainly true in this kind of work and we can both benefit by it. What do you say?”

Bob’s clear, blue eyes bored deep into Tully’s brown ones and he held out his hand.

Tully held Bob’s gaze for a moment and then his eyes shifted uneasily. He made no motion to take Bob’s proffered hand.

“Well, if that’s the way you feel about it, I’m glad that we have had a definite understanding,” said Bob.

“I guess that’s the way it’s got to be,” said Tully slowly. “I don’t like you, Bob, and there’s no use in making any bones about it. I’m going to solve this case even if I have to step all over you in doing it.”

“Well, Tully, you just run along and do your best; but I’m serving fair warning on you right now that if you try to step on any of my toes, you’ll wish you hadn’t. There’s only one way to play this game and that’s to play it fair and square. I’m going to play it that way and I’m going to win and nothing that you can do will stop me. If it is humanly possible that case will be solved within the next few weeks.”

Tully looked squarely at Bob.

“Is that a challenge?” he asked.
