G OING ON A TREASURE HUNT. X marks the spot. It's a children's rhyme for a reason. While wealth can be lost or stolen, and even found again if husband-and-wife treasure hunters Sam and Remi Fargo are on the case a long-forgotten map is just the stuff of bedtime stories. Like Long John Silver and Robin Hood. But when Sam and Remi try the unthinkable-a relaxing vacation and a visit to a rare-book store a very real dead body sug-gests what they hold in their hands is an actual, ink-on-paper guide to a historic fortune. When the Fargos take up the challenge, they find themselves flying from California to Arizona, from Jamaica to England. Racing against a vi-cious corporate raider with an unhealthy obses-sion for this particular treasure, Sam and Remi are slowed by a new betrayal at every turn. It can only mean one thing: someone on their team cannot be trusted.
