Kirsten finally finds the ‘K’ reference book that was missing on Ed’s bookshelf. Ed left the book in a safe deposit box. Kirsten unlocked the box with the key Ed hid in her mother’s tomb. Kirsten skimmed through every page, but she didn’t find anything.
Good thing Kirsten let Cameron in on the secret. Cameron notices that the gap between the hard cover and the binding is too big. Ed hid something for Kirsten in that gap.
