Ephraim Jenkinson is a gifted criminal. He’s a smooth talker who is very skilled in the art of disguise. With the help of his footman Abraham, Jenkinson convinces Moses to spend the money Moses earned from the sale of his horse, Colt, on reselling spectacles—an obviously ill-advised business venture. He also successfully scams Flamborough in the same way. Later, Jenkinson is able to cheat Dr. Primrose too, as his elaborate speeches on cosmology and praise of the vicar’s theological tracts convince Dr. Primrose to let his guard down and accept a draught (a promissory note) on Flamborough instead of payment. Dr. Primrose and Jenkinson meet again in the gaol after Jenkinson’s crimes have caught up with him; striving to repent, Jenkinson helps Dr. Primrose as best he can, making his cell more comfortably and attempting to convince him to submit to the Squire to expedite his release. Jenkinson plays an essential part in proving Squire Thornhill’s guilt, as he confesses to having helped the Squire procure women and apprehends their former accomplice, Timothy Baxter. Even more crucially, Jenkinson reveals that he in fact obtained a genuine marriage license for the Squire and Olivia, not a fake one as they believed. While this was done for blackmail, not for charitable reasons, it prevents the Squire from seizing Miss Wilmot’s fortunes and restores Olivia to honor. Sir William gifts Jenkinson a small fortune as thanks for his actions, and Dr. Primrose promises to convince Flamborough to drop the charges against Jenkinson.
