Envelope Trick is employed by Martin Lomasney.

It takes place at the Democratic convention at the Maverick House. In the race for a state senate seat, Daniel Rourke (backed by Lomasney) must compete with William Donavan (backed by P.J. Kennedy and other ward bosses) to file their nomination papers at the State House by 5 p.m. Both dispatches couriers with envelopes to for the ferry to downtown Boston. But Lomasney drops another envelop with Rourke’s actual papers out a window to a third courier, who makes use of a waiting tugboat across the harbor, and arrives at the State House one minute before Donovan’s papers arrive. Despite the efforts by Lomasney (best known for the political advice, “Don’t write when you can talk; don’t talk when you can nod your head.”), the Boston Ballot Commission subsequently rules that Donovan is the legitimate nominee and he goes on to win the election.
