Parson Kelly by A.E.W. Mason

The devil in all this affair, it was that Wogan could not be in two, or even three, places at once. While Kelly was shut in with Lady Oxford earlier, Mr. Wogan, as he has said, was on the wrong side of the door. There he was again, after the rout, while he conversed with Colonel Montague in the street. Again, while Wogan was busy with Mr. Scrope in St. James's Park, Kelly and the Colonel were exchanging their unknown explanations, of a kind not admired by Mr. Wogan, which ended in their walking, like a pair of brothers, towards George's rooms. In all these conjunctures Mr. Wogan's advice, could he have been present, might have been serviceable, or at least his curiosity must have been assuaged.

What did pass between Kelly and Lady Oxford when the rout was over, and what were the considerations which induced George and the Colonel to resist their natural and mutual desire for an honourable satisfaction?
