Hardcastle and McCormick (1983)

S1E3 Man in a Glass House

In “Without Sin,” the memoir of ex-mobster Joseph Cadillac, Hardcastle is taken aback by the harsh critique aimed at him. Concerned that the mob, which also faces Cadillac's scrutiny, might retaliate, he enlists Mark to keep an eye on the author. To Hardcastle's astonishment, Cadillac eventually approaches him seeking assistance.
