Jack Higgins does an exemplary job in creating rich characters, suspensful plot, and a suprising ending. Harry and Max Kelso become real to the reader, and it is heartbreaking to realize that as a reader of a novel, there is nothing one can do to aid the twins in their perils. This is an excellent read, and it becomes impossible to stop reading. As a student, it is difficult for me to find time for things such as recreational reading, but I just had to make time to finish this one! Thank you, Mr. Higgins, for this incredibly captivating and touching story! I recommend this book to everyone!
