- You may be looking for Maid Mackenzie.
Insector Mackenzie arrived at the house during or prior to 1883. Smith used hypnosis on him and put him into suspended animation in a drawer. In 1883, the Seventh Doctor revived him by clicking his fingers constantly in front of his face.
The Inspector then set about continuing the murder investigation and soon reasoned that something was not right. After Light woke and decided to destroy all life on Earth, he killed Inspector Mackenzie and turned him into primordial soup that he then placed on the dinner table. (TV: Ghost Light)
