"Not at all by any means; I am clever, me, but not that clever. No, my friend, I am as much in the dark as you, only I do not refuse to credit what our young friend tells us. I believe the things he has related happened, exactly as he has recounted them. I do not understand, but I believe. Accordingly, I must probe, I must sift, I must examine this matter. We see it now as a group of unrelated and irrelevant occurrences, but somewhere lies the key which will enable us to make harmony from this discord, to gather these stray, tangled threads into an ordered pattern.

When we were so filled with fasting that we could not eat another morsel my old friend took me to another priest, a native of New Orleans whose stock of local lore was second only to his marvelous capacity for fine champagne. _Morbleu_, how I admire that one! And now, attend me very carefully, my friends. What he disclosed to me makes many hidden mysteries all clear:
