Count Krinkelfiend's Quest (in Which We Meet a Vampire by a Campfire) by Gary Morecambe
When princess of Gertcha realises that Walter, the King's head servant, has gone missing, it doesn't take her long to figure out who's the culprit. (Probably because the culprit-dastardly Count Krinkelfiend-sent a note, explaining.) Luckily, Inspector Klaw has already decided that the evil Count requires some investigation and who better to come to the Inspector's aid than the celebrated vampire scholar, Professor Erich Von Morcumstein? Together, they must find the Count's lair, rescue Walter from certain death (or at least from being turned into a rat) and thwart Krinkelfiend's evil plans to become utterly invincible.it's a good thing they've got a bit of help-from a most unlikely ally.
