A strange madwoman, not answerable for her murders, and yet so lucid in her blindness, so logical in her mental derangement, so intelligent in her absurdity! What skill, what perseverance, what cunning contrivances, at once abominable and admirable!

And Lupin, in a rapid view, with prodigious keenness of outlook, saw the long array of bloodthirsty adventures and guessed the mysterious paths which Dolores had pursued.

He saw her obsessed and possessed by her husband's scheme, a scheme which she evidently understood only in part. He saw her, on her side, looking for that same Pierre Leduc whom her husband was seeking, looking for him in order to marry him and to return, as queen, to that little realm of Veldenz from which her parents had been ignominiously driven.

And he saw her at the Palace Hotel, in the room of her brother, Altenheim, at the time when she was supposed to be at Monte Carlo. He saw her, for days together, spying upon her husband, creeping along the walls, one with the darkness, undistinguishable and unseen in her shadowy disguise.

And, one night, she found Mr. Kesselbach fastened up . . . and she stabbed him.

And, in the morning, when on the point of being denounced by the floor-waiter . . . she stabbed him.

And, an hour later, when on the point of being denounced by Chapman, she dragged him to her brother's room . . . and stabbed him.

All this pitilessly, savagely, with diabolical skill.

And, with the same skill, she communicated by telephone with her two maids, Gertrude and Suzanne, both of whom had arrived from Monte Carlo, where one of them had enacted the part of her mistress. And Dolores, resuming her feminine attire, discarding the fair wig that altered her appearance beyond recognition, went down to the ground-floor, joined Gertrude at the moment when the maid entered the hotel and pretended herself to have just arrived, all ignorant of the tragedy that awaited her.

An incomparable actress, she played the part of the wife whose life is shattered. Every one pitied her. Every one wept for her. Who could have suspected her?
