This is an account of the life of the Dundalk-born Leopold McClintock who journeyed four times to the Antarctic, searching for anything to do with the lost expedition of aging British explorer John Franklin and his 129 men. The book is well-researched, making good use of McClintock's memoir and letters, and the writing is clear and pragmatic. McClintock's big claim to fame was the 1859 discovery of a hand-written and printed note, recording the death of Franklin, in 1847, as well as various other deaths that had taken place by 1848. The rest of the men would follow suit and there has been plenty of debate over their loss with various theories offered, from starvation to lead poisoning from the canned food. McClintock also revolutionised the use of dogs pulling sledges while charted hundreds of miles of new geography. Quite naturally, once this part of his life is dealt with, his story falls flat with his return to civil life but that's not Murphy's fault. Mapping the Antarctic whilst solving a Victorian mystery about the vanishing of 130 men is a hard act to follow!
