Milord Arsouille, 2nd chapter, The Infernal Machine, No. 3. The police proceeded to a minute investigation of the machine itself. - Who gave you this letter? - One of the soldiers posted at the door. Dear Prefect, the man behind the attack is no other than Jacques Montbrun, editor of the "Republican Monitor". An investigation of his domicile, Cité de coq hardi, in Belleville, shall prove his guilt …. - Let's investigate this Jacques Montbrun. Back home, Milord Arsouille was haunted by what he saw on the Boulevard du Temple. - If I had denounced Fieschi, I could have prevented this massacre. Nina waited anxiously for the return of her stepfather. - The police! ... - I'm Mr. Montbrun's cleaning lady, I have his key. - How long has Mr. Montbrun been away from his home? - He hasn't been back since yesterday …. These guns are similar to those in the infernal machine! … and here's a plan of the machine! - All show that Montbrun was one of the planners of this attack! Watch more in No. 4.
