"Episode 3" features series regulars Kyle MacLachlan, Michael Ontkean and Ray Wise, and introduces Sheryl Lee's second role, Maddy Ferguson.
The episode received positive reviews from critics, with its mix of comedy and tragedy seen as a highlight, and Miguel Ferrer's character Albert Rosenfield singled out as a particularly successful example of this.
However, other inhabitants of the town have their own suspicions: the violent, drug-dealing truck driver Leo Johnson (Eric Da Re) is seen as a possible suspect.
When she leaves, Cooper discusses his dream with Sheriff Harry S. Truman (Michael Ontkean), believing it to be a coded solution to the murder.
Cooper's colleague, Albert Rosenfield (Miguel Ferrer) wishes to conduct a further post-mortem on Laura's body, but it is due to be released for the funeral that day.
That night, Cooper, Truman, Deputy Hawk (Michael Horse) and Ed Hurley (Everett McGill) meet at the RR Diner.
He also explains that the woods around the town seem to contain a "darkness", and reveals that there is a secret society of men gathered to stand watch against this: the Bookhouse Boys.
Meanwhile, sawmill owner Josie Packard (Joan Chen) tells Truman, her lover, that her sister-in-law Catherine Martell (Piper Laurie) is scheming to take over the mill.
[7] The episode introduces the character of Maddy Ferguson, Laura's nearly identical cousin, the second role in the series played by Sheryl Lee.
Lee had been a stage actor living in Washington, where "Pilot" was filmed, and had remained there after production moved to Los Angeles as she believed that, with her character dead, she would have no further part in the series.
[8] Rathborne chose to open the episode with a shot centered on Sherilyn Fenn, finding the actress to be "seductive" and "absorbing" in a similar manner to screen icon Marilyn Monroe.
[22] Television Without Pity's Daniel J. Blau praised the episode's black humour, singling out in particular the scene in which Ferrer's character is punched after an argument in the town morgue.
