Plot Outline:
A man wanted for stock fraud is found garroted in his apartment, and the crime is eerily similar to a murder committed a year earlier, a case in which Don closed when an ex-con confessed. Now, Don must re-investigate the old case to determine if he put an innocent man in jail. He asks Charlie to go over the evidence to see if he missed anything the first time around.
