“It’s the same thing. Guarding each door is an individual, one who always tells the truth and another who always lies. You can’t know which is which, nor which door is guarded by whom—and you have one question, to one guard, to discover the correct door. Ms. Next, are you ready to play Liars and Tigers?”

“A tiger? A real tiger?”

“All eight feet of it.” Julian smiled, enjoying himself again. “Teeth one end, tail the other, claws at all four corners. Are you ready?”

“If it’s just the same to you,” she said politely, “I’ll be getting on my way.”

In a flash, Sparkle had pulled out a shiny automatic and pressed it hard into her cheek.

“You’re going to play the game, Next,” he growled. “Get it right and you win today’s super-duper prize. Get it wrong and you’re tiger poo. Refuse and I play the Spread the Dopey Cow All Over the Kitchen game.”

“Can’t we form a circle of trust, have a cup of herbal tea and then discuss our issues?”

“That,” said Sparkle softly, a maniacal glint in his eyes, “was the incorrect answer.”

His finger tightened on the trigger, and the two guards both covered their heads. This had gone far enough.

“Wait!” I shouted.

Sparkle stopped and looked at me. “What?”

“I’ll take her place.”

“It’s against the rules.”

“Not if we play the Double-Death Tiger-Snack game.”

Sparkle looked at Thursday5, then at me. “I’m not fully conversant with that one,” he said slowly, eyes narrowed.

“It’s easy,” I replied. “I take her place, and if I lose, then you get to feed us both to the tiger. If I win, we both go free.”

“Okay,” said Sparkle, and he released Thursday5, who ran and hid behind me.

“Shoot him,” she said in hoarse whisper.

“What about the herbal tea?”

“Shoot him.”

“That’s not how we do things,” I said in a quiet voice. “Now, just watch and listen and learn.”

The two guards donned steel helmets, and Sparkle himself retreated to the other side of the room, where he could escape if the tiger was released. I walked up to the two individuals, who looked at me with a quizzical air and started to rub some tiger repellent on themselves from a large tube. The doors were identical, and so were the guards. I scratched my head and thought hard, considering my question. Two doors, two guards. One guard always told the truth, one always lied—and one question to one guard to find the correct door. I’d heard of this puzzle as a kid but never thought my life might depend upon it. But hey, this was fiction. Strange, unpredictable—and fun.
