Schadenfreude

Plot:

The team investigates the early 1980's murder of a surgeon's wife. The husband had been convicted of the murder and was thought to have committed it for insurance money. The couple was under financial pain as a result of the doctor being sued for malpractice after he accidentally caused the death of one of the family's best friends on his operating table. However, new evidence found on a dead junkie with a past connection to the victim causes the case to be reopened.
