Tinkerbell is considered one of The Diamond Circle's most influential operatives despite displaying remarkably little enthusiasm for physical activity. Investigators believe she maintains authority through silence, intimidation and a highly developed ability to make everyone around her feel deeply disappointing.

Although the suspect spends much of each day asleep on premium cushions, heated blankets and sunny windowsills, surveillance suggests she remains fully aware of everything happening nearby. She has an uncanny ability to appear the moment food, affection or royal treatment becomes available.

Intelligence indicates that Tinkerbell answers directly to Beatrice Diamond and is occasionally entrusted with sensitive Diamond Circle assignments. Most operations are delayed, however, until the suspect has completed her current nap and decided the matter is worthy of her attention.

Despite her reputation as The Lazy Assassin, investigators believe her inactivity may be deliberate. By remaining perfectly still and appearing completely uninterested, Tinkerbell encourages others to lower their guard before delivering one of her trademark expressions of total disapproval.

Fellow members of The Diamond Circle appear to treat Tinkerbell with an unusual level of respect despite her relaxed attitude. Investigators believe this is partly due to her calm judgement and partly because nobody has ever been brave enough to wake her when she is sleeping. As a result, the suspect has earned an almost untouchable reputation within the organisation.
