When an art fraud investigator receives a package containing a stolen diamond from a man claiming to be her long-lost brother, she discovers that her father masterminded an international diamond heist and then travels to Geneva and underground catacombs in the Siberia wilderness to locate the stolen diamonds and return them to their rightful owner in order to save her father, who she thought was dead, from the consequences

Just clarity I would drop “art” as there isn’t really an art fraud division in the police, it is normally just fraud. Plus the art and diamond seem to have no connection.

Thrust on a journey seems wrong. I would use thrust to demonstrate a start of none stop action “thrust into a fight to the death”. Most journeys are even paced.

Are all these things linked if so, describe how. Does the cryptic glue lead her believe that her family is involved? Why head there, what is she hoping to learn or achieve. Why wouldn’t she just let local authorities handle it? I’ll assume it is looking bad for her family and she hopes to clear their name. As an example.

After receive a package containing a stolen diamond and a cryptic message from her dead brother a fraud detective heads to Siberia to discover the truth and prevent her family from being implicated in an international cold case.

A little wordy but it show direct links between the elements.

I can see what you are trying to achieve but there isn’t enough story to allow me to see what I would be getting.
