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!
