Does a stolen antique car hold the clue to a secret fortune?

Husband and wife treasure-hunting team Remi and Sam Fargo head to England to help Viscount Albert Payton recover a fortune that was lost a hundred years ago - along with the family's good name.

It is believed this treasure was linked to the theft of a Rolls-Royce prototype called the Grey Ghost, which legendary detective Isaac Bell helped to recover, while the treasure itself remained missing.

But then the Grey Ghost is stolen once again - this time from right under the noses of the investigating Fargos.

And the Viscount vanishes too.
