Publisher's Synopsis
From his cell in the health prison, Arsène Lupin plays big, very big!
What mysterious enterprise is bringing Rudolf Kesselbach, the extremely wealthy and ambitious South African diamond king to Paris? What does this number, 813, signify on the box in his possession? What secret does the named Pierre Leduc, whom he searches for in the lowlands of the capital, hold?
These are some of the questions over which the police - in this case a certain Lenormand, head of the police -, the ruthless Baron Altenheim and the gentleman-burglar Arsène Lupin, clash. Who will also have to unmask the invisible assassin who seeks to make him bear responsibility for his crimes ...
And here we are, in the footsteps of the orphan Geneviève, the elegant Prince Sernine and many other characters, in an avalanche of drama and revelations, each more incredible than the next.
