Harold and Chester could hardly believe it. The Monroe family was going on vacation without them! Bunnicula, the family rabbit, would be boarded with a neighbor. But they, the family's loyal dog and cat, were to stay with strangers at the foreboding Chateau Bow-Wow...

No sooner had Harold and Chester settled into their bungalows than Louise, a French poodle involved in a messy love triangle, disappeared. Chester believed the six other guests were capable of anything -- even murder. Would you trust a pair of dachshunds who howled at the moon and were rumored to be part werewolf? Or crazy Lyle, a cat convinced he was a secret agent?

All Harold and Chester knew was that in spite of themselves they had entered the crime detection business and neither foul play nor foul weather would stop them from finding out whodunit!

The Monroes have gone on vacation, leaving Harold and Chester at Chateau Bow-Wow -- not exactly a four-star hotel. On the animals' very first night there, the silence is pierced by a peculiar wake-up call -- an unearthly howl that makes Chester observe that the place should be called Howliday Inn.

But the mysterious cries in the night (Chester is convinced there are werewolves afoot) are just the beginning of the frightening goings-on. Soon animals start disappearing, and there are whispers of murder. Is checkout time at Chateau Bow-Wow going to come earlier than Harold and Chester anticipated?

Harold and Chester could hardly believe it. The Monroe family was going on vacation without them. Bunnicula, the family rabbit, would be boarded with a neighbor. But they, the family's loyal dog and cat, were to be sent away with strangers; they were to spend a week at Chateau Bow-Wow.

Chateau Bow-Wow, observed Chester, soon after they arrived, could more properly be called Howliday Inn. Though what was howling, neither of them knew. Chester had his suspicions however; only a werewolf could make that chilling sound.
