The power of plausible deniability. Andrew knows Will's greatest power is his stolid honesty. The same honesty places Andrew in the lonely spot of not sharing this ticking bomb with Will. He also can't use all the resources at his command because it'll leave a trail.
The Knot Sunk Yet is at the bottom of the river, but the proud ship Will is still sailing, for now.
Now we know what the card meant. It's a smear job. I find it impossible to believe Will would be unfaithful. At least Andrew has a jump on this to cut it off.
Chance connections have brought them to this point, Blake to Pitt on Absolute, the capture of Belle Therese, attracting the attention of the Chevalier de Guise, and now admiral Rowley. They both held their own. Attention can be bad or good. For now it's to the good side.
British law of the period is interesting. Since a baronet isn't a peer, he's tried in court. Until 1841, there was no punishment for peers on a first offense, except for treason or murder. The House of Lords only tried 30 cases, with 29 getting death. So peers of the realm were virtually immune from prosecution or arrest. Which is why Granger in Odyssey could laugh at Maidstone's man after George bribed a guard to release Dr. Jackson from prison where he was to be hanged.
I wondered about Vane getting away with his nasty letters while on lockdown. Huxley got beaten by Vane's once. It wasn't happening again. Now all his tongue can do is hang his conspirators with him.

"Let's go home.", says more about where he wants this to go than anything.
