Poison laboratory

Laboratory 12 was a Soviet assassination laboratory that used poisons to kill its victims. People were poisoned in broad daylight and they were indefensible even if they knew it was coming. One of the more interesting cases involved a man who knew he was being targeted. He holed himself up in a hotel with guards. The assassins sprayed a poisonous substance on the lamp shade and when the lamp was turned on hours later, the substance evaporated due to heat and killed everyone in the room.
