When Jack moves to Doggeroo with his landlord, Sarge, he finds a mystery on his paws. Who is stealing his stuff? Who is making a dog den in a deserted house? Who owns the old boot in Jack's new yard? Jack is soon hot on the trail of a criminal, but what he discovers is entirely unexpected. In the course of his investigations, he meets Lord "Red" Setter, the streetwise Foxie and many other characters who will become familiar friends - and enemies - in the series. Dog Den Mystery is available as an audio book from Bolinda Audio Books wonderfully read by Alan King. This book is also available in the USA, (under the same title), in the UK (where it is called "Dognapped"), and in Canada, under the title of "Le Voleur de Bottine".
