Perceiving that he was face to face with a disguised man, Juve was about to hurl himself on this masquerader, when that individual, forestalling the detective's movement, seized the initiative with lightning rapidity. He tore his hand from Juve's tenacious grip, bounded to the mantelpiece, threw down the lamp with a jerk of his elbow, thrust Juve violently aside, and rushed to the door.
Like lightning Juve tore off in pursuit.
The masquerader had the advantage by some yards. Banging door after door in Juve's face, he rushed towards the entrance hall, gained the staircase, racing down it by leaps and bounds, four steps at a time!... Juve at his heels, risked breaking his neck in hot pursuit....
Vagualame reached the porch of the house door: Juve was close on his quarry....
"I shall get him!" thought Juve: "In the street the people will lend me a helping hand!"
Vagualame fled through the doorway: in passing, he seized the massive door and pulled it to with a resounding bang....
Juve, borne forward by the impetus of his dashing pursuit, staggered backwards and rolled to the ground....
Instantly Juve sprang to the porter's lodge and demanded the string! In the twinkling of an eye and Juve was out in the street! He was furious, he was breathless.... The whole length of the pavements not a soul was in sight! Vagualame had vanished!
Taking advantage of the fact that Fandor's concierge knew him well, and was aware of his standing as an officer of the detective force, Juve, after having explained in a few words to the honest creature the cause of the commotion mounted to Fandor's flat once more.
