The house of death - P. C. Doherty

First volume in the magnificent new mystery series featuring Alexander the Great; It is 334 BC and the young Alexander sits with his troops by the Hellespont, poised to attack the empire of the great King Darius III. To win the approval of the gods for his enterprise he makes many offerings, yet the smoke does not rise, the sacrificial animals are flawed. Worse, his guides are being brutally murdered, Persian spies are in the camp, and Alexander's generals have their own secrets. Into this turmoil comes telamon, a physician, and boyhood friend of Alexander. As the climax builds and Alexander throws off his nervous fears, winning a brilliant and bloody triumph over the Persians, Telamon at last succeeds in unmasking their enemies.
