A wooden fence of lattice-work, rather more than three feet high, was all that separated the Widow Chupin’s garden from the waste land surrounding it. When Lecoq made the circuit of the house to cut off the murderer’s escape he had encountered this obstacle, and, fearing lest he should arrive too late, he had leaped the fence to the great detriment of his pantaloons, without even asking himself if there was a gate or not. There was one, however—a light gate of lattice-work similar to the fence, turning upon iron hinges, and closed by a wooden button. Now it was straight toward this gate that these footprints in the snow led the two police agents. Some new thought must have struck the younger man, for he suddenly paused. “Ah!” he murmured, “these two women did not come to the Poivriere this evening for the first time.”

“Why do you think that, my boy?” inquired Father Absinthe.

“I could almost swear it. How, unless they were in the habit of coming to this den, could they have been aware of the existence of this gate? Could they have discovered it on such a dark, foggy night? No; for I, who can, without boasting, say that I have good eyes—I did not see it.”

“Ah! yes, that is true!”

“These two women, however, came here without hesitating, in a straight line; and note that to do this, it was necessary for them to cross the garden diagonally.”

The veteran would have given something if he could have found some objection to offer; but unfortunately he could find none. “Upon my word!” he exclaimed, “yours is a droll way of proceeding. You are only a conscript; I am a veteran in the service, and have assisted in more affairs of this sort than you are years old, but never have I seen—”

“Nonsense!” interrupted Lecoq, “you will see much more. For example, I can prove to you that although the women knew the exact position of the gate, the man knew it only by hearsay.”

“The proof!”

“The fact is easily demonstrated. Study the man’s footprints, and you, who are very sharp, will see at once that he deviated greatly from the straight course. He was in such doubt that he was obliged to search for the gate with his hand stretched out before him—and his fingers have left their imprint on the thin covering of snow that lies upon the upper railing of the fence.”

The old man would have been glad to verify this statement for himself, as he said, but Lecoq was in a hurry. “Let us go on, let us go on!” said he. “You can verify my assertions some other time.”
