" I've always known that the Tarzan series evolved into an outlandish, serial-like collection, but I didn't realize how quickly it escalated. We're only in the second book of the series and already our endearing, primal, jungle god is embroiled in espionage and smoking cigarettes. Burroughs could have devoted an entire novel to Tarzan's struggle of assimilation, while wrapping up some important loose-ends from the first book without resorting to theatrics. I was entertained but not touched. "
