The first time the members of the McGurk Organization became aware of Dennis, the invisible dog, was at their celebration "Annual Picnic" - as a doughnut flew off the picnic table and floated down into the bushes. When the young detectives investigated, they made an amazing discovery - the invisibility Machine, invented accidentally by Brains Bellingham, when he was trying to get rid of Dennis's fleas. McGurk had to have that machine for his organization - even if it meant Brains had to join, too. But when the invisible dog ran away and McGurk led the search, he discovered some clues that led to some very suspicious questions!
E.W. (Edmund Wallace) Hildick was a British children's book author. He was born in Bradford, England in 1925. After two years service in the Royal Air Force he became a secondary school teacher, then a writer, later moving to the United States to become editor of a literary magazine. He died in London in 2001.
It’s still jarring for me to read the American version of a McGurk book, although now I can absolutely see how Hildick would have rewritten elements for both audiences and what a clever trick that was for him to pull off. As ever, it’s less of a mystery than I remembered them being, but is fun in a sort of introduction to impossible crime in the style of John Dickson Carr. The solutions are simple and neat but probably pretty eye popping for a young reader, and the general lesson of the book - you may be a smart arse but we absolutely respect your ability to pull off being a smart arse, so please join our club so you can be our very own smart arse - is incredibly heartwarming
