An enjoyable quick read.I did not like the character Vern but Chet, as usual, sparkled like a shining star. I am always amazed how strong the Hardy Boys are as they seem to overpower almost any body-builder they see.A good mystery.Although I must note it is strange reading/rating a children's book. I want to discredit its pace, short sentences and lack of description but I know it would not be fair because its target audience are 8-13 year olds. All in all it's another good edition to the long running series and I cannot wait for my nephews to inherit them from me.PS - Dolphin Shark rescues FTW.
