This is not my latest read...but of the "most-times-read-books" during my school days :

Of course, I read the Thamizh translation only and never the English translation that is in this link. (Original was possibly Russian as the writer is Yakov Perelman, the Thamizh version was made in erstwhile USSR and of top-quality material, distributed by NCBH in India those days).

Go to the "pdf" tab to read in that format. I would recommend jumping to PAGE 98, for a very thrilling story!
