six in the morning
To procure himself this gratification he had already expended six francs in visiting all the reading rooms of Paris without being able to find `` The Beaver '' in any one of them . Not being able to stand it any longer , Colline swore to himself that he would not take a moment 's rest until he had laid hands on the undiscoverable editor of this paper . Aided by chances which it would take too long to tell in detail , the philosopher was able to keep his word . Within two days he learned Rodolphe 's abiding place and called on him there at six in the morning . Rodolphe was then residing in a lodging house in a deserted street situated in the Faubourg Saint Germain , and was perched on the fifth floor because there was not a sixth . When Colline came to his door there was no key in the lock outside . He knocked for ten minutes without obtaining any answer from within ; the din he made at this early hour attracted the attention of even the porter , who came to ask him to be quiet .
