The gentleman thief returns in this intricately plotted tale of disguises, loot, and love. Once more Lupin is at large, snatching fortunes from under the noses of the wealthy. But this time he may have met his match . . . and not in his usual nemeses, Inspector Ganimard or Holmlock Shears, but in a bright school student who manages to penetrate his secrets -- and reaches his treasure-trove! But the greatest danger may be the woman with whom Lupin has fallen in love, for she has made him promise to give up his life of crime forever!
Raymonde listened. The noise was repeated twice over, clearly enough to be distinguished from the medley of vague sounds that formed the great silence of the night and yet too faintly to enable her to tell whether it was near or far, within the walls of the big country–house, or outside, among the murky recesses of the park. She rose softly. Her window was half open: she flung it back wide. The moonlight lay over a peaceful landscape of lawns and thickets, against which the straggling ruins of the old abbey stood out in tragic outlines, truncated columns, mutilated arches, fragments of porches and shreds of flying buttresses. A light breeze hovered over the face of things, gliding noiselessly through the bare motionless branches of the trees, but shaking the tiny budding leaves of the shrubs. And, suddenly, she heard the same sound again. It was on the left and on the floor below her, in the living rooms, therefore, that occupied the left wing of the house. Brave and plucky though she was, the girl felt afraid. She slipped on her dressing gown and took the matches.
