“Could you tell if she were pretty, or whether she was a blonde or brunette?”

So many questions at a time confused the driver. “Stop a minute!” he replied. “In my opinion she wasn’t pretty, and I don’t believe she was young, but she certainly was a blonde, and with plenty of hair too.”

“Was she tall or short, stout or slender?”

“Between the two.”

This was very vague. “And the other,” asked Lecoq, “the neatly dressed one?”

“The deuce! As for her, I did not notice her at all; all I know about her is that she was very small.”

“Would you recognize her if you met her again?”

“Good heavens! no.”

The vehicle was now rolling along the Rue de Bourgogne. Half-way down the street the driver pulled up, and, turning to Lecoq, exclaimed: “Here we are. That’s the house the hussies went into.”

To draw off the silk handkerchief that served him as a muffler, to fold it and slip it into his pocket, to spring to the ground and enter the house indicated, was only the work of an instant for the young detective.
