Professor Fergus MacLeod

In the short story The Augean Stables, Professor Fergus MacLeod is a scientist and an acquaintance of Hercule Poirot. Poirot had a great deal of respect for the eighty-two year old Professor and regarded him as one of the greatest scientists and brains of the day. MacLeod had once told Poirot that Edward Ferrier, the Prime Minister, was a one of his students and that he was "a sound man". To Poirot this was a compliment of the highest order. It motivated Poirot to agree to help Ferrier in the difficult challenge of clearing up a financial mess left behind by the previous Prime Minister John Hammett.
