It was handed down in slightly different versions by various people; one version is contained in a letter from Freud to Stefan Zweig: I was in a position to guess what really happened with Br’s patient long after we parted company when I recalled a communication from Br dating from the time before our joint work and relating to another context, and which he never repeated.
Seda anti eri versioonides edasi; üks versioon on Freudi kirjas Stefan Zweigile: Ma suutsin ära arvata, mis tegelikult Br-i patsiendiga juhtus tükk aega pärast tema seltsist lahkumist, kui mul meenus vestlus Br-iga, mis on pärit ajast enne meie ühist tööd ja seostub teise kontekstiga, mida ta enam kunagi ei korranud.
