Of all the Spooks 'verses I've written
Lucas the Werewolf has to be my favourite. Lucas was deliberately turned while in the Russian jail, but with the support of Section D, and in particular Adam's assistance, he remains a valuable part of the team.
The werewolf loves a good party, and is very fond of his food. In his lupine form he resembles a large dog, with a luxuriant coat, which gives him the ability to get closer to people who would otherwise be suspicious, but are unaware of the transmitter in the smart collar he's wearing. Harry Pearce isn't as sure of the werewolf, who he suspects might be deliberately winding him up, but is unable to do anything about it.
The werewolf sat quietly and watched as the various party guests mingled. He looked longingly at the buffet table on the far side of the room, but knew he had to stay where he was.
Suddenly an altercation arose and, at the same time across the room someone collapsed, bleeding profusely. Quickly, the werewolf made for the open doors leading into the garden and collided with a small man, knocking him over, causing him to drop a knife. The werewolf stood guard, waiting for help, and in the meantime, relieving the man of the sausage roll from his other hand.
