Dupin served as model for the later creations of Sherlock Holmes and Hercule Poirot, among others of this particular school of fictional detectives. Read more here. Dupin would appear in two other Poe stories: THE MYSTERY OF MARIE ROGET and THE PURLOINED LETTER. Read about the short stories here.
Poe has always held a special place in my heart, most especially because while in school (at a very tender age), we were made to memorize and recite his poetry. (Ah, the good old days of public school (in NYC) when literature and poetry were revered and we actually learned a thing or two.) THE RAVEN and ANNABEL LEE and the one about the bells were popular, if I remember correctly. Some of the lines still linger, most are lost to memory. But I still retain affection for it though probably, at the time of forced memorization I was not as fond of the poems as I should have been.
