At least he suspected Hamilton, and was seeking him more diligently than ever before.

His Majesty had not shown me any mark of disfavor, but I feared he suspected me, and was sure he was not convinced that Frances's alibi had been proved by unsuborned testimony.
If he was sure that she was the one who had been kidnapped, his suspicious nature would connect George with the rescue, and would lead him to conclude that Hamilton must be in England.
A maid of Lady Castlemain's told Rochester, who in turn told me, that the king had again set his men to work searching for Hamilton.

That being the case, George was in danger, and should he be found by the king's secret agents, who, I understood, were prowling all over England in the hope of obtaining a reward, his life would not be worth a week's purchase.
George knew the risk he ran by remaining in England, but it was a part of his reckless courage to take delight in it.

Later on this recklessness of disposition induced him to take a far greater risk.

But of that in its turn.
