Tim has worm scars from the Prentiss attack on the Institute in MAG 39. In Basira Hussain's opinion, unlike John's scars, Tim "manages to pull them off", still looking good. When compared to Martin Blackwood, Basira calls Tim "the hot one."
Tim has a First in Anthropology from Trinity College and previously worked for five successful years climbing the ladder at a major publishing house.
Tim had a younger brother, named Danny, whom he adored. To Tim, Danny was better than him in everything except for humour, but his charisma was so off-the-charts that he did not need it. In 2013, Danny's urban exploration hobby led him to the Covent Garden Theatre, designed by architect Robert Smirke and now known as the Royal Opera House. He was presumably killed there by an agent of The Stranger, the clown Joseph Grimaldi. When Danny did not return home, Tim went to the theatre in an attempt to find him. As he entered, he saw a single figure standing on the stage he thought looked like Danny, but there was something not right about his appearance. Tim found himself immobilized by "some force", which he later conceded could have just been fear. He was forced to watch, frozen in place, as the clown "pulled the skin off of whatever had been pretending it was [his] brother." Tim soon found himself outside with no memory of what happened afterwards, including how he exited the theatre. He never returned there, being convinced that if he did, they would not let him leave "a second time."
In hopes of finding out what happened to his brother that night, Tim soon began working at The Magnus Institute, desperately searching for anything related to The Circus (an organization of The Stranger) or Robert Smirke. According to Jonathan Sims, Tim had even used Institute funds to bribe filing clerks for information on at least one occasion. However, with no new helpful information, Tim gradually stopped seriously looking for answers and started to just get comfortable.
Tim is a researcher for the Magnus Institute before the newly appointed Head Archivist, Jonathan Sims, pulled him as an archival assistant. He passively continues his search for circus-related things while helping with statement follow-ups. Tim uses a variety of ways to get information, such as impersonation and flirting.
Tim is out for lunch during Jane Prentiss's siege on the Institute and is absent when the others barricade themselves inside the safe room. He comes back to the Archives unaware of the danger and is rescued by Sasha James. He attempts to escape alongside Jonathan Sims and Martin Blackwood but becomes separated from the latter in the tunnels under the Institute. He and John are both attacked by Prentiss but are saved by the deployment of the CO2 system.
Tim and John are given leave following the attack and he takes John's subsequent paranoia the worst of the researchers. He and the others confront John over his increasingly erratic behaviour but relations between Tim and John do not improve following the intervention. This comes to a head in an argument during which Tim demands sympathy, having faced the same hardships as the rest of them, but John tells him that he is still unable to trust him. When Tim attempts to quit, he realises that he and the others are somehow being compelled to stay at the Archives.
Before breaking the table binding Not-Sasha, John gives Tim and Martin the day off. The two opt to investigate instead, as Tim is suspicious of what John is going to do. They briefly spot Not-Sasha, then become trapped in Michael's corridors. They escape to see the corpse of Jurgen Leitner in John's office and assume John killed him.
Tim continues to be bitter about his work life and being trapped in his job. Elias Bouchard confronts him about his "unauthorised absences." after Tim flees to Malaysia to escape the Archives. Tim knows he cannot quit and Elias will not fire him, so he figures it is worth a try. He, like John, eventually grows weak and sick and has to return. Elias admits that the Archives are not always good for the people that work there but the best way to deal with it is to focus on your work.
Tim is present when Daisy, Basira, and John confront Elias about the murder of Gertrude Robinson in MAG 92. He is initially annoyed at John's continued paranoia but is horrified once he learns the truth about Elias and the death of Sasha. Fed up with not being told anything and not having anyone on his side, Tim later demands Martin tell him what The Unknowing. He gives Martin a statement about how his brother disappeared and how he had been working at the Institute since to find anything about what happened to him. Elias believes Tim may jeopardise John's mission and tells him to stay away from the Unknowing and the circus. Tim responds that Elias will have to kill him if he wants to keep him out of it.
Tim accompanies John, Daisy, and Basira to stop the Unknowing. Nikola distorts his perception and he becomes unaware that he is holding the detonator. However, John is eventually able to snap him out of it and he suddenly realises the situation. Enraged that her deception is failing, Nikola begins trying to reason with Tim, her desperation quickly becoming evident in her tone of voice. He tells her dryly, "You sound stressed. You know, I hear the great Grimaldi’s in town. You should go see it; cheer yourself up." Nikola replies emphatically, "That's...not...funny!" With his finger on the button, Tim sarcastically replies, "I know." Suddenly, a click is heard, followed by the first moment of a massive explosion before the audio abruptly cuts out. The explosion kills Tim and successfully derails The Unknowing ritual.
