The Golden Triangle 

As our tale opens, Arsene Lupin is but a memory. We see his picturesque grave, and perhaps we take a moment to mourn his passing. But around us a mystery comes into focus — a mystery involving Captain Patrice Belval and a one-armed African named Ya-Bon and a nurse we know only as Little Mother Coralie . . .Before the tale has tolled, Arsene Lupin will live again. There are mysteries to be resolved!‘
