Overview: Simon & Siouxsie are faced with a tricky situation when a woman spots a large snake slithering around in her garage, but loses sight of it. From her description, the snake sounds like it could be a black mamba, but Simon and Siouxsie can't confirm without getting up close and personal with the potentially deadly intruder. If it is a black mamba, the slightest mistake could be fatal, and without access to anti-venom a bite will result in death.
