When an old friend of Slim's starts an archaeological dig near the ranch, Little Alfred quickly gets caught up in the excitement. And once Alfred manages to get himself invited to the dig, it isn't long before Hank follows. There, Hank finds himself face-to-face with the most ancient of bones-a huge bison bone that Hank is sure has been aged to delicious perfection. Can Hank uphold his position as Head of Ranch Security and help protect the bone, or will his doggie instincts get the best of him? Marking the fiftieth installment to this long-running series, this bonus-length story will give die-hard Hank fans more than double the adventure to enjoy.
