“This is one of my most favorite supermysteries with Nancy Drew and the Hardy Boys. It features my favorite elements, of spy-thrilling and very mysterious. The dialouge was especially entertaining and I enjoyed seeing Nancy get more 'into' things than just blending in as she usually does. The Hardy Boys do their fair share of work, but they seem to fit the story really well and they are there for Nancy when she needs them. There is the slightest hint of romance in here, but in the end, Nancy handles it just fine and we are glad to see it. A pretty good read, if you like the old-fashioned Nancy Drew and Hardy boys slam togethers. This one is a personal favorite. ”
