Mark Elgin

Mark Elgin.

Mark Elgin was the public relations director for Global Chemicals, and also served Jocelyn Stevens in the capacity of an assistant sometimes. He was also initially one of the employees not directly controlled by BOSS. Not being controlled by BOSS meant that he was able to notice that Stevens and others were behaving strangely.

When Ralph Fell told Brigadier Lethbridge-Stewart that Global Chemicals had no equipment with which to rescue Jo Grant and Bert Pritchard from the Llanfairfach mine, Elgin knew he was lying. Jo was rescued nonetheless, although Bert was killed.

Suspecting something was amiss, he followed Fell later and caught him attempting to kill the Doctor and Jo by flooding the pipe they were in with toxic waste while they were returning from exploring the mine. He was able to overpower Fell and stop him, rescuing the pair. Fell escaped, and then later, seemingly inexplicably, ran past the three and leaped to his death.

After the Doctor and Jo left and returned to the Nut Hatch, an enraged Elgin finally confronted Stevens, who locked him inside his office and allowed BOSS to brainwash him. Shortly after this, he came down with appendicitis and had to be rushed to the emergency room. He was freed from BOSS' control when the computer was destroyed by Stevens. Years later, Elgin participated in the documentary Global Conspiracy and helped bring to light the crimes of Global Chemicals.
