Query: Weak even in title, about Nazist secret weapons

About twenty years ago, I read this weak book, about Nazi Germany secret weapons.And this book is weak even in title, about Nazist secret weapons.There's more photos, than text, in this book. This book is concise and easy to understand, but outside these advantages, this book is weak.As an example of this weakness, about V-2, there's some informations, but the author didn't wrote that V-2 production by slave's labor, killed more slaves than enemies in London.
