Maurice Leblanc 
Golden Triangle, The Return of Arsene Lupin 

The Golden Triangle is another fantastic mystery by Leblanc featuring gentleman thief Arsene Lupin. 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!" (Goodreads)
