Yeah January 35

Stangerson, daughter of a famous scientist, was found dying in his room which was completely closed and that the killer could not get out. The only trace of the passage of a man is the mark of his bloody hand on the wall and strangulation marks on the throat of Mathilde.
The police investigation is then conducted by a young reporter / interviewer, the famous Rouletabille, and his lawyer friend, Sinclair will be our narrator.

From the start, something I do not like the criticism and works of famous authors such as Edgar Allan Poe and Conan Doyle saying that nothing compares to this mystery of The Yellow Room. I had trouble linking me "friendship" with Rouletabille, I felt a certain distance from him, which was the opposite of Sainclair (the narrator) or two famous detective Sherlock Holmes and Hercule appointed Poirot.

It remains on its end by not knowing what the "perfume of the lady in black" which Rouletabille talks non-stop. In the first, it does not reveal everything and the murderer fled ... It's not the end I expected because it is mandatory to read the second volume for details.
Also, I got tired of all lengths in the descriptions, and the silencing of history. Also if I wanted to follow the plot, would have had I notice the different indices, dates, times on a sheet but a good police officer did not need that ...

Positivons a bit anyway!
I found the story well put together, there are many details, the author has an impressive imagination, the survey is conducted from beginning to end.
The revelation of the mystery at the trial in open court, is also quite nice, it is not common.
