The quotations in the text are either taken from original documents in Polar Archives or from material quoted in the referenced publications. I use these sources with thanks to the authors or editors. The staff at the Scott Polar Research Institute in Cambridge; at the National Maritime Museum in Greenwich; and at the Royal Geographical Society in London, England were extremely helpful with the research upon which this and my other Franklin-related books are based.
An excellent source for up-to-date information on the ever-continuing struggle to solve the mystery of Franklin’s third expedition as well as book reviews and links to related sites, can be found at http://www.ric.edu/rpotter/index.html
My thanks to everyone who has struggled along a bleak Arctic shore searching for a fragment of cloth or a bone which might add another piece to the puzzle.
