There were several of the three dollar bills. There were two ones. And there were five twenty dollar bills. I shoved all the money into my pocket except one of the three dollar bills.

I made sure no one was looking my way, and dropped Golfin's billfold on the floor, kicking it under the counter behind me in the center aisle where it wouldn't be found unless the janitor swept under there. I decided to do the same with Wile's. After all, if Sam Golfin were right, and there was a murder, I didn't want a couple of strange wallets on me. Nor those coated needles.
