Rajat Gupta pays his tribute to Sherlock Holmes:

That is the strength of observation and deduction. Holmes methodology as all the fans of the character will know were based on scientific analysis ,observation and deduction . Just by looking at the soil of the shoe of the person he could tell about the place from where he came. He could deduce(note the word) the past of the person just from the physical features of the person. He could judge the profession of the person looking at the shape of the hands.

Holmes seems to be so real for Rajat that he doesn’t mention the name of the writer who created him even once in the post.
