dupin read all this with great interest, and was the first to open the evening newspaper when it arrived.
He read silently, and then said, 'There is nothing new about the murders,but the police have arrested Adolphe Le Bon. Why,I don't know.' He looked at me. 'Well, my friend, what do you think about these murders?'
'It's great mystery,' I said. 'It will be impossible, surely, ever to find this murderer
'We must not say "impossible" just because the police have done nothing,' said Dupin. 'The Parisian police do find the answer sometimes, but that is usually because of hard work, not because they are clever. Very often, you see, they don't think clearly. They look very hard at one or two things, but they don't see everything. You remember the saying, "They can't see the wood for the trees"? Well,sometime it's important to stand back and look at the whole wood, and forget about the trees. Now, why don't we do a little detective work ourselves, and go round to the Rue Morgue? Adolphe Le Bon was once very helpful to me, and I would like to help him if I can. I know the police inspector, and I'm sure he will say that we can look round the house. So,shall we go?
We went that same afternoon. We found the house easily because there were still people in the street looking up at the closed shutters. It was the usual kind of Parisian house, with nothing surprising about it. Before we went in, we walked up the street, turned down a narrow side street and turned again to walk past the back of the building.Dupin looked at everything - the ground, the walls, the windows, the shutters - but I did not know what he was looking for.
