Didactylos reviewed Corners of the globe by Robert Goddard (The Wide world trilogy -- bk. 2)
Review of 'Corners of the globe' on 'Goodreads'
4 stars
Take the 39 Steps then mix in a dozen other plotlines and off we go. You are either going to like this or not. I did, thought the concept of the master megalomaniac with almost unlimited power to predict and deploy agents is hard enough to swallow in modern times, but in 1919 even less likely. However once you take that on board the narrative rattles along and the cast of characters just grows and grows.
Annoyed however that I did not realise this was the 2nd in the trilogy and that effectively it is one very long book not three.
