The condoling letter is very Fritz (in a mild way way, I hasten to add): we must all die, alas, be a philosopher, accept it, even though I totally feel your pain as a tender mother, live for me, you are the happiness of my life.

Ha! Yes. (So was the poem for Amalie that felis linked, at least from my mild browsing in google translate.)

also that people peeping through keyholes (?!) saw repeatedly that D'Argens took off his two caps which he was otherwise wearing all the time before reading the letters.

Okay, I laughed -- peeping through keyholes?? (Though it's a rather sweet story.)

(Book selling tactics are also eternal.)

Ha!
