The cause of the explosion has not yet been discovered.
I soon became involved in the affair when Hungary and Roumania began mutually to blame one another as originators of the outrage.

This led to numerous interventions and adjustments, and my task was intensified because a presumed accomplice of the murderer Catarau was arrested in Bucharest, and his extradition to Hungary had to be effected by me.
This man, of the name of Mandazescu, was accused of having obtained a false passport for Catarau.
Catarau, who was a Roumanian Russian from Bessarabia, vanished completely after the murder and left no trace.

News came, now from Serbia, then from Albania, that he had been found, but the rumours were always false.

I chanced to hear something about the matter in this way.

I was on board a Roumanian vessel bound from Constanza to Constantinople, when I accidentally overheard two Roumanian naval officers talking together.
