List of Monk Characters - Recurring Characters and Special Appearances - Warrick Tennyson

Warrick Tennyson was a career criminal and explosives expert who was hired to build the bomb in 1997 which killed Trudy (Monk's wife). Dale the Whale tells Monk that Tennyson was involved in the murder, in "Mr. Monk Goes to Jail". He tells Monk he can find Tennyson in New York. Monk goes to New York in the next episode, "Mr. Monk Takes Manhattan", in hope of answers, but finds that Tennyson is dying of heart disease and kidney failure. Because he’s being questioned in connection with a Federal racketeering case, the District Attorney is not letting anyone else see him. The only way for Monk to get access to Tennyson is to solve the recent murder of the Latvian Ambassador.

Having cracked the case, Monk's party is allowed to visit Tennyson (Collison) on his deathbed. Tennyson remembers being hired by a man to build the bomb that killed Trudy. When asked, he says he does not know the name or the description of the man that hired him, since it was dark when they met, and it looks like Tennyson is a dead end. But Tennyson remembers one vital clue: the man had six fingers on his right hand.

Monk asks for a few moments alone with Tennyson. When the others are gone, Tennyson asks for forgiveness, but Monk cannot bring himself to give it. He turns off Tennyson's morphine drip. But a few tense moments later, he turns it back on, saying "his is Trudy, the woman you killed, turning it back on".
