Plot Summary

When the Enterprise arrives a few days early at its rendezvous point to meet the USS Victory, the crew have a bit of leisure time on their hands. For Data and Geordi Laforge, it means a trip to the holodeck and 221B Baker St. With Data in the role of Holmes and Laforge as Dr. Watson, they take on a challenge from Dr. Pulaski that Data couldn't solve a genuine mystery. Data has a bit of time adjusting to a real mystery - as opposed to one for which he knows the outcome. In giving the holodeck computer its instructions however, Geordi's specifications for an opponent results in a far superior creation than expected putting them and the entire ship in danger.

Did You Know?

Trivia Although it is commonly believed that Sherlock Holmes has been in the public domain since sometime before the 1980s, the Sir Arthur Conan Doyle estate maintained copyright on the character - a claim set to expire in 2023 - until their claim was voided by a court ruling in 2013, ten years ahead of the planned date. Paramount Studios (producing company of the Star Trek franchise) obtained permission from the Doyles to make Young Sherlock Holmes (1985) (acknowledged in that movie's end credits), but considered similar permission unnecessary for "Elementary, Dear Data," which they believed fell under the parody clause of copyright law, and thus aired the episode without notifying the Doyles. (ST:TNG producer Jeri Taylor, who joined the show in 1990, once incorrectly wrote that Paramount was wholly ignorant of the Doyles' property, but Doyle attorney Jon Lellenberg straightened this out.) The Doyles then wrote to Paramount that they were flattered by the episode, but felt it remained within their legal sphere, so they wanted in on any further Trek usage of their characters. Although Brent Spiner was eager to play Holmes again, nearly 4 years went by before Paramount and the Doyles agreed on a "reasonable licencing fee" for the sequel Ship in a Bottle (1993). See more »
Goofs Moriarty hands Data a piece of paper upon which is a sketch of the Enterprise. Data immediately storms off the holodeck, and shows the paper to La Forge. As the paper was holographic, it should have vanished the moment it was removed from the holodeck. However, other episodes have established that some objects (such as food) are actually replicated within the holodeck, and thus are "real" (i.e. not holographic), depending on the needs of the program and its user (as well as the plot of the individual show).

Quotes Moriarty: Is the definition of life "Cogito ergo sum" - I think, therefore I am?
Captain Jean-Luc Picard: Yes, that is one possible definition.
Moriarty: It is the most important one - and for me, the only one that matters.
