“I won’t say for free. I can show you a trick. You’ll have the chance to see something that’s likely beyond the bounds of your common sense.”
“A magic trick?”
“Yes. I’ll be frank... it’s quite something. You’ll be amazed.”
Saber spoke with an innocent smile like a child’s. The police officers exchanged glances, smirked, and decided to play along with the madman.
“Ha. In that case, why don’t you show us what you can do in your condition?” one of the officers said.
Saber nodded, smiling, raised his cuffed hands and gave them a shake.
“I have nothing in my hands. Do you agree? Look closely.”
“...Yeah.”
“...And now, I’m going to disappear.”
“Huh?”
The officers were puzzled, not quite taking in the man’s meaning. Then... Saber’s body vanished like mist. His handcuffs, left hanging in the air, fell to the table with a loud clatter. “...!?”
“Wha...”
The officers were all on the verge of panicking. They ran their eyes over their surroundings, stretching hands to the pistols and stun guns at the hips.
“Where’d he go?”
“What happened?”
“Do not open the door!”
The uproar continued... but as soon as they took their eyes off the man’s chair for a moment, he was back in his original position. The only difference from before was the handcuffs, which were lying empty on the table.
