Collected by Mr. Kipling Steve after they were sent on a case that involved victims of murder who seemed to have been shot, but there were no traces of bullets involved. Steve found out that the victims were linked loosely by a contract that their families had signed generations ago over a plot of land, and the murderer was using the cards to kill them off so the land could be up for sale. Luckily they tracked down the killer before they could kill the last person who was said to inherit the land was killed, and got the cards in the process.
