Long thought lost,[1] it is available on DVD as part of Twentieth Century Fox Home Video's Charlie Chan Collection, Vol.

It is the first entry in the series to feature actor Keye Luke, who would become a mainstay in his role as Chan's "Number One Son" Lee.

[citation needed] Chan is on his way back from completing the London case—they always mentioned the previous case—to go on "vacation" to Paris, but this is just a way to make people think that he is innocently there.

After a police officer escorts Xavier away, Chan calls his assistant, Nardi, who promises to talk with him later about new information she found out.

That night, Chan, Max and his girlfriend, Yvette, and Victor go to a cafe/club, where Nardi works as a dancer.

After her performance, she is thrown into a room by her dance partner (part of the routine), where Marcel murders her by throwing a knife at her.

Her last words to Chan instruct him to look in her apartment, where he finds a letter hidden in a cuckoo clock which explains that Albert is spending beyond his income.

As Chan leaves Nardi's house, Marcel throws a giant rock down in an attempt to kill him, which fails.

She is jailed by the inspector, but Charlie points out an overlooked clue: footprints leading to Albert's room.
