The History of Henry Esmond by William Makepeace Thackeray

As characters written with a secret ink come out with the application of fire, and disappear again and leave the paper white, as soon as it is cool; a hundred names of men, high in repute and favoring the Prince's cause, that were writ in our private lists, would have been visible enough on the great roll of the conspiracy, had it ever been laid open under the sun. What crowds would have pressed forward, and subscribed their names and protested their loyalty, when the danger was over! What a number of Whigs, now high in place and creatures of the all-powerful Minister, scorned Mr. Walpole then! If ever a match was gained by the manliness and decision of a few at a moment of danger; if ever one was lost by the treachery and imbecility of those that had the cards in their hands, and might have played them, it was in that momentous game which was enacted in the next three days, and of which the noblest crown in the world was the stake.

From the conduct of my Lord Bolingbroke, those who were interested in the scheme we had in hand, saw pretty well that he was not to be trusted. Should the Prince prevail, it was his lordship's gracious intention to declare for him: should the Hanoverian party bring in their sovereign, who more ready to go on his knee, and cry, "God Save King George? " And he betrayed the one Prince and the other; but exactly at the wrong time. When he should have struck for King James, he faltered and coquetted with the Whigs; and having committed himself by the most monstrous professions of devotion, which the Elector rightly scorned, he proved the justness of their contempt for him by flying and taking renegade service with St. Germains, just when he should have kept aloof: and that Court despised him, as the manly and resolute men who established the Elector in England had before done. He signed his own name to every accusation of insincerity his enemies made against him; and the King and the Pretender alike could show proofs of St. John's treachery under his own hand and seal.
