The killer left one glove at the murder scene and used it to extort money from Ulla and Raul. The killer demanded ransom in drachmas for the glove's return, while Ulla tried to leverage it for more money and avoid provoking the killer further. This extortion plot was part of the killer's broader plan to manipulate passengers.

Foreshadowing: The extortion scheme revealed the killer had financial motives beyond simple murder.

Ulla was killed because she was actively trying to use the glove to blackmail the killer. Ida Tuclidis broke into Ulla's apartment, drowned her roommate first, then killed Ulla by slamming a bathroom door shut on her. Ulla's attempt to profit from the glove made her a threat to Ida's anonymity.

Foreshadowing: Ulla's greed in demanding higher ransom sums put her directly in the killer's path.

Yes, Luciano was completely innocent. The Inspector revealed at the end that Luciano was framed from the start. While he was the prime suspect due to his letter opener being the murder weapon, he had nothing to do with the killing. His improvised investigation and cooperation actually helped uncover the real plot and potentially saved lives.

Foreshadowing: Luciano's persistence in proving his innocence despite being cornered showed his genuine lack of guilt.

The young safe cracker created a mask from Ulla's recovered head bust to lure Ida Tuclidis into a trap. By wearing the mask at the fashion show, she used Ida's own vanity and guilt about Ulla's death against her. This clever ruse forced Ida to expose herself when she confronted what she thought was Ulla's ghost, leading to the rooftop confrontation.

Foreshadowing: Ulla's vanity in sponsoring a bust of her own head became the tool used against her killer.

The Lebanese traveler was actually a narcotics officer secretly tracking Ida Tuclidis' drug trafficking activities. He remained in the background throughout the investigation, watching the unfolding events while waiting for an opportunity to bring down her operation. His presence explained the web of criminal connections that motivated Ida's killing spree.

Foreshadowing: His careful observation of other passengers suggested he was gathering intelligence, not simply traveling.

• narcotics officer
• drug trafficking
• undercover

The ending remains deliberately unclear about whether all threats were eliminated. While Ida Tuclidis fell from the rooftop and the Inspector confirmed Luciano's innocence, the Lebanese narcotics officer continues pursuing her trail. The film suggests danger may have simply faded into the shadows, leaving open whether other conspirators or threats remain active.

Foreshadowing: The constant paranoia and hidden identities among passengers suggested the criminal network ran deeper than single arrests.
