West and Gordon ensure that the Crown Jewels of Herzburg arrive safely at the Denver museum where they are to be exhibited, only for them to disappear almost immediately from a locked room. The agents become suspicious of Axel Morgan (John Doucette), a wealthy rancher, when Gordon notices that a painting which Morgan donated to the exhibit is a forgery. It soon emerges that Morgan is in collusion with Dr. Loveless. This time the mad genius has invented a way of entering and leaving paintings via the use of sound waves. He's also sent for master gunslinger for Lightnin McCoy (John Alonzo), whom he plans to employ in a showdown with West.
Tropes present in this episode:
- Artistic License Physics: This is applied liberally throughout the series, but it's usually subtle enough that suspension of disbelief can cover the discrepancies. Usually. When this episode shows people hopping in and out of paintings through the use of sound, however... just... no.
- Bandito: Lightin' McCoy turns out to be one of these.
- Duel to the Death: This is what Loveless hopes to set up between West and McCoy. The agents manage to foil his plans... mostly - the two men still end up squaring off. Not surprisingly, Jim wins.
- Fastest Gun in the West: Lightnin' McCoy, reputedly. When put to the test, it turns out he is - er, was - second best, at most. Loveless has also gathered the second through seventh fastest guns to serve as his henchmen (and backups in case McCoy fails).
- Girl of the Week: Averted big time - this is the only episode of the series with no female characters at all.
- Locked Room Mystery: Loveless uses his sonic device to transport people and objects into and out of locked rooms by hiding them inside paintings.
- Portal Picture: The story is built around this trope.
- The Starscream: Axel Morgan to Dr. Loveless. Neither is very willing to play second banana and after a lot of infighting, Morgan finally attempts a double-cross.
- Stating the Simple Solution: Axel Morgan advises Dr. Loveless to just kill West immediately. Loveless does not take this advice well; in a variation of Only I Can Kill Him, he really wants to see a showdown between West and McCoy.
- The Stoic: Lightnin' McCoy. When West outdraws him, he simply says to Loveless, "He was very fast, Señor."
- Trojan Horse: Dr. Loveless plots to hide assassins in a collection of forged paintings and then donate the paintings to various world leaders. The assassins will then emerge and kill the leaders, thus allowing Loveless to rise to power.
