Franklin never answers Abbé Nollet's attacks, and his silence pays off. Le Roy defends him in Paris, and French scientists repeat his lightning experiments before the king at Marly. Philosophers across Europe adopt his ideas over Nollet's, and Nollet lives to see his own school fade. The Royal Society in London elects Franklin a member, waives his fees, and gives him the Copley Medal, all without his asking. Governor Denny even brings the medal to Philadelphia at a city dinner and praises Franklin's long-known character.
Back in Pennsylvania, Denny pulls Franklin aside after drinking and hints that rewards will follow if he stops fighting the proprietors. Franklin says his own circumstances make favors unnecessary and that he will support only measures that help the public, not the proprietors alone. When disputes continue, he remains the Assembly's active penman against bad instructions, though he and Denny stay personally friendly. The Assembly then sends him to England as its agent when the governor blocks a defense grant, but Lord Loudoun first forces a temporary compromise and then keeps Franklin stuck in New York for months while packet ships wait for letters that are always promised for tomorrow.
A messenger named Innis jokes that Loudoun is like Saint George on a tavern sign, always on horseback and never riding. Loudoun detains passengers for months, drags packet boats to Halifax on a useless exercise, and leaves the frontier exposed while Fort George falls. Franklin compares him unfavorably with the sensible General Shirley, who took a low seat at a dinner rather than complain. Loudoun also refuses to pay Franklin for Braddock's certified supply accounts and says everyone in army contracts fills his own pockets. Franklin says he charged no commission and pocketed not a farthing, but Loudoun tells him to collect in England instead, and the balance remains unpaid as he finally sails after months of delay.
On the voyage Franklin watches the crew move water casks aft to fix a sluggish ship, bets on log-line speed with a navy captain, and nearly hits a lighthouse in fog, which makes him resolve to build more of them in America. He reaches London in July 1757 with his son, stops to see Stonehenge on the way, visits Dr. Fothergill and Lord Granville, and hears the startling claim that the king's instructions are the law of the colonies. Talks with the proprietaries go nowhere, their lawyer Paris delays everything, and the memoir breaks off mid-fight over Pennsylvania taxes, with Franklin's international fame earned but his political work still unfinished.
