Farewell, Great Macedon (audio story)

Publisher's summary
The TARDIS materializes amidst the Hanging Gardens of Babylon, where the Doctor and his companions meet Alexander the Great. Four members of Alexander's retinue, however, are plotting to murder the king and his successors so that one of their number, Seleucus, can ascend to the throne and allow them to return to their homeland. The conspirators try to frame the time travellers, but the Doctor and Ian succeed in a series of trials and Alexander's bodyguard, Ptolemy, proves their innocence. However, history cannot be changed, and despite the Doctor's efforts to save the king's life by having Ian build an iron lung, Alexander dies while Ptolemy helps the companions escape to the TARDIS.
