These 2 biographies took the writer, according to him, 2 years each to write.
2nd volume is just released. Both narrates the story briskly.
Written in an easy-to-read vocabulary, one can finish them in 4 days.
Unfortunately, these biographies do not have an index and footnotes to support statements made.
Thus, we await a more scholarly biography due to the absence of these 2 components in the 2 books here.
