All that was a set-up. Mr. Ozel was not in America by the time Clen visited to kill him. He was in China with Zours and the rest. The person Clen had shot was not Mr. Ozel. The house Clen was spying inside on was no longer Mr Ozel's as he had sold it off about five days earlier. Everything was a set up and even the money involved was a fake promise as no installmental payment was done.
Clen had been too greedy to analyse the offer. A million dollars for a single kill was far too suspicious for a normal assassin but Clen thought that either Solomon Wroth Wis wanted to waste his money or he was ignorant.
Mr Ozel if ranked in terms of amount for a kill was worth about two hundred dollars for am assassin like him.
The police saw the building collapse after the bomb detonated. A lot of queries and questions banged in their heads as they tried to think of the possibility of what had happened. In order to investigate further, they trooped into the building.
