Annabel Lake

 was a human who met the Doctor when she was a little girl. Her mother died shortly after their first meeting, and Annabel held a grudge against him since then. She became involved with an unknown organization with the codename of Cheshire and moved to Cornucopia with her father under the alias of a Toliakk called Miss Ghost. She met the Doctor again there twice.

Biography
Annabel was born in England, but moved to Prague with her parents as a young girl. Her father told them that he worked as an accountant and that he had been transferred there, when in truth he was a spy working for the British Embassy investigating Yuri Azarov. In November, 1989, Annabel and her mother, Heather, were kidnapped by Azarov. Here they met the Doctor, who was also being held captive. They discovered the Golem of Prague and freed him from Yuri's control. The Doctor sent Annabel to sleep and, while she was asleep, Heather became the Golem to save the world from the Mavora, but was destroyed. Her last words were "No-one threatens my daughter!"

At some point, presumably helped by her father Patrick's job as a spy, Annabel became affiliated with some sort of space organisation and investigated psychic metal under the alias of Cheshire. Annabel and Patrick had moved to Cornucopia by 2012. (COMIC: ''Hunters of the Burning Stone)

At this point, Annabel was working for Granny Solasta, the overlord of Cornucopia, disguised as a Toliakk called Miss Ghost. Here she met the Doctor for a second time, as he and his friend Rory were captured by Solasta, who wanted to use the TARDIS to get to the Bank of Heaven, a ziggurat made from the psychic metal which Annabel was investigating and which was sending Cornucopia into poverty. The Doctor was forced by Solasta and the other crime lords of Cornucopia to take them to the bank, where he tricked them into fighting over its riches. Annabel tried to stop them but thought better of it, choosing to save herself. The Doctor managed to destroy the ziggurat and escaped with Amy, Rory, Horatio Lynk and Annabel. The Doctor then correctly deduced that 'Miss Ghost' wasn't a Toliakk, and Annabel turned off her disguise. However, the Doctor had no idea who was under the suit as he had not yet met Annabel as a child and she didn't take off her helmet anyway, instead hinting that she knew him and that she'd be seeing him again soon.

After Granny Solasta's death, Annabel and Patrick continued to live on Cornucopia. Annabel was still disguised as Miss Ghost, and was now working in port authority. Continuing her investigation into psychic metal, she boarded Captain Pala's ship, using a sonic screwdriver to access information. However, her cover was blown just after she found stores of liquid psychic metal. While the ships crew were attacking her, the ship wasattacked by the Hunters. Annabel grabbed a member of the crew, Tarky Pakko, and questioned him. She found out that they got the liquid from a mining ship in the Kell Nebula. She destroyed the liquid metal just before the Hunters could get to it, prompting them to destroy the ship. She opened a portal to escape and Pakko begs her to take him with her. She asked him where the mining ship was heading, and he told her that he didn't know. She After Solasta's coldy tells him that he's no use to her and leaves him behind on the exploding ship.

The Hunters proceeded to attack Cornucopia. Annabel followed them and once again met the Doctor, this time accompanied by Ian Chesterton. She demanded that he told her what he knew of the Hunters, and took Barbara Wright hostage. Barbara struggled and they both fell back into Annabel's portal. They emerged on Annabel's ship, where Barbara confronted her and demanded to know who she was. She took off her helmet and introduced herself as Annabel Lake and revealing that she blamed the Doctor for her mother's death. (COMIC: Hunters of the Burning Stone)
