Oscar the Mole is a chef, but all his life he dreamed of becoming a private investigator. He knows how to find the right path in the pitch darkness and knows that the key to solving a problem is the ability to notice important details... But there is a catastrophic lack of a case he could take on!
And then suddenly an entire squirrel has gone missing!
Isn't that a great excuse to prove himself in action?

From the author's interview:

'I believe that it takes a lot of effort and perseverance to do what you love. So I created a character who is completely unsuited to what he wants to do, but he still tries, and - amazingly! — he can do it.
Therefore, I would recommend reading the books about Detective Mole to anyone who dreams of becoming someone, but is afraid to try: if the mole can do it, then anyone can do it!
