Digging up Trouble...Hank the Cowdog is on the case in his 50th mystery, and it's an extra long, laugh-out-loud adventure!

But Hank's heart isn't the only thing that's about to get stolen!

The head of ranch security and his first lieutenant, Drover, are finishing up an exhausting morning of patrols when a mysterious caravan of trucks rumbles past headquarters. Going in for a closer look, Hank the Cowdog apprehends a large red box bearing a mysterious label: "WARNING! MONKEY! DO NOT OPEN THIS BOX!"

An eye for an eye. Things are looking pretty bleak for Hank the Cowdog. First he gets sick on poisoned bacon grease. Then he accidentally trips Sally May - and she ends up with a broken ankle. And if that's not bad enough, he gets stuck playing dress-up with Amy and Ashley, Little Alfred's cousins. But when Tuerto the Killer Stud Horse breaks free and charges at the girls, Hank knows it's up to him to protect them. He'll show that one-eyed horse who's boss - even if it means risking his own life!

"I do have an idea. The most important thing, though," I said to Margot, Mrs. Marvin, and Catherine, "is for you to act completely normal. Our big advantage is that the thief doesn't think that anyone will check the safe until we're already back in River Heights and he or she is off the boat. The culprit has no idea that we're looking for him or her."

I glanced over at the digital clock I had placed on the nightstand; it read 3:19 a.m. I had been fast asleep for hours - what had woken me up?
