Maurice Leblanc 
Golden Triangle, The Return of Arsene Lupin [EPUB ebook] 

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)
