Archibald "Archie" Doyle is an assassin for the Knights of the Teutonic Order in the Copernicus Legacy series. An eccentric and deadly killer, he is assigned to take out the Guardians of the 12 Copernicus relics. Doyle is a master of disguise and often goes unnoticed until it's too late.
In the series
The Serpent's Curse
Archie Doyle is first introduced when Ebner von Braun requests backup help in catching the Guardian Kaplan family as they head to Russia to find the Serpens relic. A call is sent to Doyle, who is just waking up. He is very annoyed, however, when Ebner's message says just to follow the Kaplans, and not terminate them. He prepares his assassin gear (disguises, tools, and a Bulgarian umbrella) and sets off, telling his wife that he will be home late that day.
As the Kaplan family talks to Boris Rubashov (a Guardian) in a London restaurant, Doyle sneaks into the cafe unnoticed and stabs the Russian with the poison umbrella tip. Boris suddenly falls over and dies, while Doyle watches the scene. Ironically, Becca, a friend of the Kaplans, thinks he is a doctor and asks for his help in saving Boris. Doyle says he is not a doctor.
Later on, Doyle tracks the Kaplans to Boris's apartment, disguised as an old man. The Kaplans are busy inside investigating and watching the Guardian tape Boris had. He knocks and when let in, Becca sees through his disguise and pulls his fake beard off. Doyle wields his Bulgarian umbrella while the Kaplans throw objects such as books and a lamp at him. In the end, Becca throws a video player at his head, stunning him and allowing Darrell to throw his Bulgarian umbrella down a stairwell.
At the very end of the book, Galina Krause sends a message to Doyle saying to immediately terminate the Kaplans. Ebner says this will make him happy.
Becca and the Prisoner's Cross
Doyle is sent to find the Kaplans again. The family now has the help of Guardian Terence Ackroyd, who knows of Doyle's assassin skills. Doyle tracks them to a train station near Bletchley Park, but is recognized. To keep him off their tracks, Lily and Wade Kaplan put their hats on a group of random teenagers that look like them. Doyle follows the teens onto a subway train, which takes off just as he realizes it is too late.
Doyle is able to find the family again due to a bug placed on Becca's bag by an Order agent. He disguises himself as an elderly man to enter the Bletchley Park Library. Wade converses with him. Right as a librarian Guardian is going to help them decode a puzzle, Doyle removes his disguise and attacks the librarian. However, the Kaplans throw a phone monitor at his head and trip him under a chair. He starts shooting randomly; this attracts security to enter. Doyle escapes the unarmed guards and goes after the Kaplans in a coding machine shed. They plan an ambush, where Wade throws gravel in his face as the other run. As Doyle breaks into the shed, he is tripped by a table, but still pursues them. Terence and Dr. Kaplan arrive in a car, letting the kids enter. Terence then rams Doyle with the car, sending him flying and letting the now-armed guards tackle him.
Doyle somehow escapes the police and finds the Kaplans at St. Andrew's Church, where a standoff for the Crux relic is occuring. He holds Wade at gunpoint, but Wade is able escape by climbing up the stairs of a bell tower, followed by the assassin in pursuit. Becca follows them, and the two teens fight Doyle. Wade smashes a window during the chaos, and he and Becca push Doyle out of the tower, where he falls to his death.
In The Golden Vendetta, Ebner von Braun remarks on how after Doyle's death, the order to kill the Kaplans had to be halted due to Galina Krause being stuck in a 2-month coma and a lack of competent assassins.
Although he is a cold assassin, Archie Doyle has an eccentric and lively side. When attempting to stab the Kaplans with his Bulgarian umbrella, he wields it like an actor in a stage duel. He often yells almost cartoonish phrases, such as yelling "What are you looking at?!" and firing his gun when a bystander screams at him.
He is similar to Boba Fett in many ways (both are assassins with many tools who attack a main character and died at the hands of heroes who didn't know they would kill him).
