In this final volume of Graeme Lay's fictional trilogy on the life of James Cook, we confront a very different man to the legend or, for that matter, the first two books in the series.
The Cook we met before was calmly efficient, possessed of both good luck and wisdom, an outstanding seaman and navigator, who - by the standards of the time - treated his crew humanely and showed a sure touch in dealing with the natives of the places he visited.
Now, on his third voyage of discovery, we face an older Cook (he turned 50 on the voyage) who is sick, subject to intemperate outbursts, treats miscreants with brutality, makes crucial mistakes and has a run of ill fortune.
Even the tone of the private journal Lay has him keeping for his wife, Elizabeth, changes from matter-of-fact descriptions of events to querulous accounts of things gone awry, filled with complaints about a sore leg, constant pains in the stomach, constipation and sleeplessness.
Where did it all go wrong? The book points the finger at an event early in the voyage while the expedition was recuperating at Ship Cove in the Marlborough Sounds. The chief responsible for massacring a boatload of mariners from an earlier expedition came on board the Resolution and, instead of being punished, was given gifts, enraging the crew and earning the contempt of Maori.
