When the inmate Jeremy Kent questions his case to the parole board, the CSIs are forced to reopen his case from eighteen years ago. Kent was accused of murdering the ninety-one-year-old Thomas Harriot in the first solo-case of Catherine. The bruises suggested that the victim had been struck two blows to the head with a blunt instrument like a hammer that was never found. The only evidence was a stone with Kent's fingerprint used to break the window. Now Kent is claiming that he found Harriot dead and he only found the dead body. The CSI' have to use state-of-art technology to reinvestigate the case and prove that Catherine was right, but they discover he had a partner.
"If I Had a Hammer..." is the best episode of "CSI" after the departures of Warrick and Grissom. This show recalls the first episodes of this great series, with lot of investigation of the team. Jeremy Kent's plan backfired in the end, involving someone that he did not want to be brought to the case. My vote is eight.
Title (Brazil): "If I Had a Hammer..."
