There are many characters in my IRB, a collection of Ray Bradbury's most celebrated short stories. The one I have chosen to see how Bradbury developed him is Sir Robert Merriweather, from The Finnegan. The Finnegan is about a murder mystery in which three young children were discovered after having been drained of all of their fluids. There are three characters in this story: the narrator, Sir Robert Merriweather, and the Finnegan, the culprit behind the murders. Sir Robert Merriweather is introduced as a modest man who is apparently a very observant old man, comparable to Sherlock Holmes. He is also obsessed with doors, as it is described there being anywhere from a hundred and twelve to a hundred and twenty doors in his house. He is described as an avid collector as well, having not used one in nine of his doors after having shipped them from all over the world. He had doors from America, Rio, Paris, Rome, and even Tokyo. He is proud of his collection too, because he sets them up, hinged, in the walls so they can be seen from both sides and conducting tours of them for anyone who wished. He is also shown to be a thinker who likes to think outside of the box, in that he after analyzing the facts, states that the police were anthropomorphic about the killer, thinking him a human. Merriweather, on the other hand, states that the killer is in fact a giant spider, which he has dubbed Finnegan. Bradbury has so far set up Merriweather to be brilliant, but eccentric as he decides to go out for a picnic and drags the narrator along, stating that a secondary purpose was to show the author his hypothesis. Merriweather is also very accepting of the outlandish, as he does not see any problem with the idea of a giant, man-eating spider. In the end, he also shown to have a rather pragmatic side, as he wishes to see Finnegan before he dies. He knows that even if Finnegan does not kill him, cancer will, so he drinks poison and uses himself as bait for Finnegan, both to satisfy his curiosity and to kill the giant spider.
