On Costigan, Sullivan, Brown and Berrigan
Regarding the final confrontation between Costigan, Sullivan, Brown and Berrigan, Benjamin Franklin (himself a Bostonian) said this: "Three can keep a secret if two are dead." In this case when it was revealed that Sullivan was a mole inside the MSP, Costigan, Brown, and Berrigan (who was a mole as well), all four had a secret and three died. 😀
