This is a bad book. Serialized by Argosy starting in 1910, published in this volume in 1912. As much as I appreciate an early appearance of radioactivity in popular fiction, its treatment is ludicrous. As much as I appreciate an early appearance of the wicked Asian criminal mastermind in popular fiction, its treatment is awful. An ending with multiple tissue-thin love matches.
I will rid myself of this book. Do not accept it from me.
