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

Wife-and-husband treasure-hunting team Remi and Sam Fargo head to England to help Viscount Albert Payton recover a fortune that was lost along with the family's good name a hundred years ago. It is believed this treasure was linked to the theft of a Rolls-Royce prototype called the Grey Ghost which legendary detective Isaac Bell long-ago helped recover. Unfortunately, the treasure itself is still missing.

But when the Grey Ghost is once-more stolen - this time from right under the noses of the investigating Fargos - and the Viscount himself also vanishes, Remi and Sam know this mystery has taken another twist.
