47- Poisoned Beer

  I went inside the tavern, which was relatively empty. My man had hauled up on a bar stool and was addressing the bartender. I went over there and took a seat two down from him. I saw that Old Man Maintenance had ordered a beer, so I told the bartender I’d have what that guy had.
...

  When the guy was done with his drink, I offered to buy another. He accepted. I ordered one for me as well. When the bartender delivered them, I went over and sat beside the fellow. We clinked our glass mugs and said, “Cheers.”

  People have many strange rituals.

  We drank those down, then both lifted our mugs. Waved them at the bartender and asked for refills. I had palmed one of the vials Birdie sold me and emptied it into the dregs of the guy’s beer before it was filled again.

  After one more round, which the maintenance man bought, I left. Found a cheap motel, got a room, and slept soundly with no bad dreams.
