While this was cute and fun it wasn't something an adult can really derive much from except vicariously by reading it to a kid and seeing how they like it. Since it is aimed at kids, then on that basis, I consider it a worthy read. For me as a grown-up, not so much!
This audiobook is of the original story, first published in 1958, and it features Basil the mouse, who lives in the basement of 221B Baker Street where he learned his detecting craft from listening to Sherlock Holmes solve his cases. Starting out as what appears to be a simple case of missing children, things turn all around when an unruly mob trio threaten all resident mice in the Baker Street basement 'village'. Basil takes exception and resolves to cut the case off at the knees before the villains can make good their threat. He and his assistant Dawson don disguises and head north to run down the villains in their lair. They could of course have simply let the villains move in, then called the mouse police on them, but this seems never to have occurred to Basil.
Like I indicated, the story is simple and innocent, and at times amusing, and should delight young children. I consider it a worthy read for them.
