I read that review here in an Australian paper. It sounds great. Foster was so popular here that the Cornish Association regard him as a sort of honorary Cornishman. Misconceptions have been spread around about him since about the 1970s and it's really sad. It's worth taking a look at the memorial site where his true story is related. It's here:
