Whoever next gets something from the plothole will find this letter.
Cher Chris,
Come to Paris. It's perfectly safe. The Terror is over. I want you to see our lovely flat and some of the sights.
Please bring someone with you, since the way is still a long trip for a lady in your condition. Walk to Blakeney Manor through the garden gate and you can reach Paris from there.
All my love,
Armand
