Never Judge a Book By Its Cover (S05E12)

Lovejoy escorts Charlotte to an Antiques Fair in Cambridge, where the financially struggling Doncaster sisters request his expertise in valuing their possessions. During his assessment, Lovejoy uncovers what appears to be an extremely rare bible, but the sisters' brother, a Cambridge scholar, is against selling it. As Lovejoy investigates further, he realizes the bible is actually a counterfeit, leading him to suspect foul play. Meanwhile, Beth's father is urging her to pursue a more promising opportunity away from Lovejoy Antiques.
