Dr MacDougal

In the novel Three Act Tragedy, Dr MacDougal is the principal doctor in Loomouth. Miss Milray calls him to Crow's Nest when Rev Stephen Babbington is taken ill and dies during the house party at the beginning of the novel. Dr MacDougal says that Rev Babbington suffered a seizure, and points out that he was elderly, and that his health had not been good. At the inquest, he says that there is nothing to show that death did not arise from natural causes.

Dr MacDougal is not featured in the Ustinov film Murder in Three Acts (1986). There is a Doctor Vega played by Martin LaSalle.

In the ITV David Suchet episode Three Act Tragedy (2010), Dr MacDougal is not featured.
