Hmm... I just found the book yesterday at a second=hand books sale. I'm a third way through it. Quite interesting and a good read. However, reading some of the comments called my attention to some points;<br>Apparently, I'm reading and abriged and edited version made by Scholastic Book Services in 1973. The uncle is Professor Von Hardwigg of Hamburg, Germany and his nephew by his English sister-in-law is Harry Lawson. All else so far runs the same.
