Dr Dakers

In the short story The Adventure of Johnnie Waverly, Dr Dakers was the doctor who attended to Ada Waverly when she was taken ill, on the night before the day the kidnappers had warned her son would be kidnapped. Dr Dakers concluded that she had been poisoned but that it was not serious--she just needed to stay in bed for a few days.

Dr Dakers was not featured in the film adaptation of the story in episode 3 of Series 1 of ITV's Agatha Christie's Poirot drama series.
