The seventh book. No, I'm not going to go all the way through numbering them, but these are close enough to the beginning for it to seem more significant, at least to me.

Nero Wolfe's daughter is introduced, and Balkan politics are discussed, and the pre-war political and commercial jockeying for position is noted. And Nero Wolfe's history is made more and more confusing. Sometimes he's born in the US, sometimes not. He definitely spent a lot of time in the Balkans. That house in Egypt—sometimes he's never seen it.
