Fyodor Dostoyevsky 
The Double 

-THE DOUBLE- centers on a government clerk who goes mad. It deals with the internal psychological struggle of its main character, Yakov Petrovich Golyadkin, who repeatedly encounters someone who is his exact double in appearance but confident, aggressive, and extroverted, characteristics that are the polar opposites to those of the toadying ‚pushover‘ protagonist.  
 
The motif of the novella is a doppelganger (Russian ‚dvoynik‘), known throughout the world in various guises such as the fetch.

It was a little before eight o’clock in the morning when Yakov Petrovitch Golyadkin, a titular councillor, woke up from a long sleep. He yawned, stretched, and at last opened his eyes completely. 
For two minutes, however, he lay in his bed without moving, as though he were not yet quite certain whether he were awake or still asleep, whether all that was going on around him were real and actual, or the continuation of his confused dreams.  
 
Very soon, however, Mr. Golyadkin’s senses began more clearly and more distinctly to receive their habitual and everyday impressions. The dirty green, smoke-begrimed, dusty walls of his little room, with the mahogany chest of drawers and chairs, the table painted red, the sofa covered with American leather of a reddish colour with little green flowers on it, and the clothes taken off in haste overnight and flung in a crumpled heap on the sofa, looked at him familiarly. At last the damp autumn day, muggy and dirty, peeped into the room through the dingy window pane with such a hostile, sour grimace that Mr. Golyadkin could not possibly doubt that he was not in the land of Nod, but in the city of Petersburg, in his own flat on the fourth storey of a huge block of buildings in Shestilavotchny Street.
