Selina made it out of the museum undetected and headed home to get some rest.
She had planned to put the necklace in a safe where she kept her other loot, but catching sight of herself in a mirror she stopped to admire the necklace. It was made of gold and despite being thousands of years old it looked brand new. In the middle of the necklace was a golden cat's head with jewels for eyes.
Selina decieded she did not want to remove the necklace. Stripping off all her clothes, she climbed onto her bed wearing nothing but the necklace. Stretching out like a cat she quickly fell asleep.
