==Fictional character biography==
The Cluemaster starts his criminal campaign by a daring but unsuccessful attempt to learn Batman's identity and gain a fighting edge.<ref name="dc-ency"/><ref>''Detective Comics'' #351</ref> He returns to [[Gotham City|Gotham]] for a rematch with Batman,<ref>''Batman'' #201. DC Comics.</ref> then appears in several supervillain crowd scenes over the years.<ref>''Batman'' #293&ndash;294, ''Batman'' #336, ''Crisis on Infinite Earths'' #9, ''Batman'' #400. DC Comics.</ref>

With several other villains, Cluemaster becomes a member of the [[Injustice League]], a team of out-of-luck supervillains who, when banding together, become even less successful than they have been in their individual careers.<ref>''Justice League International'' #23. DC Comics.</ref> The Injustice League have been defeated time and again by the [[Justice League International]], at least when they are not making laughingstocks of themselves. Trying to reform, the members later become the core of the equally laughable hero team Justice League Antarctica.<ref>''Justice League America'' Annual #4. DC Comics.</ref> They help out the Justice League when JLI liaison [[Maxwell Lord]] lies in a coma,<ref>''Justice League America'' #53. DC Comics.</ref> but again later reform as the Injustice League as henchmen of [[Sonar (comics)|Sonar]].<ref>''Justice League Europe'' #49&ndash;50. DC Comics.</ref>

Cluemaster reappears in ''[[Detective Comics]]'' #647 by Chuck Dixon and Tom Lyle. In this three-issue story, Cluemaster has reformed and been released from [[Blackgate Penitentiary]]. Cured of his compulsion to leave clues, Cluemaster originally joins a gang and plans their heists in exchange for 10 percent of their winnings. He later kills the leader by suffocating him with a strong [[polymer]] over his mouth and nose, and begins to plan a master heist.

During this time, it is revealed that Arthur Brown / Cluemaster has a daughter named Stephanie through a woman named [[Crystal Brown]], but rarely spends any time with her due to long periods of incarceration. Stephanie is furious when she discovers that he has returned to crime without his need to leave clues behind. Making a costume for herself, she calls herself The Spoiler, finds out her father's plans, and leaves clues so that the police and Batman can stop him.<ref>{{cite book |last1=Greenberger |first1=Robert |title=The Essential Batman Encyclopedia |date=2008 |publisher=Del Rey |isbn=9780345501066 |pages=92–93}}</ref> [[Robin (character)|Robin]] spots Spoiler on the rooftops during a police bust of Cluemaster's apartment and unmasks her, though she incapacitates Robin by hitting him in the face with a brick. Robin tracks her down and Batman, Robin and Spoiler set a plan in motion to take down Cluemaster. Spoiler was forbidden from going to the bust because she was only motivated by revenge. Catching Cluemaster at his mall heist whilst he hauls a giant glass canister of money away by air, Stephanie is then held hostage by Cluemaster atop the canister, holding a vial of acid to her face as Batman tries to stop him. Batman tells Cluemaster to stop and Cluemaster, thinking Batman will only lecture him about how it is morally wrong to disfigure a child, is taken aback when Batman simply reveals Spoiler is his daughter. Spoiler uses the shock of the revelation to gain the upper hand and uses one of the chains attached to the Gunship lifting the canister to strangle Cluemaster, but Batman prevents this. Cluemaster is taken back to Blackgate.<ref name="dc-ency"/>

Each time the Cluemaster escapes or start some new plan, Stephanie dons her costume again to foil him. Eventually, she realizes she enjoys being a hero, and begins regular patrols as Spoiler. For a brief period of time she even replaces her boyfriend, Tim Drake, as Robin.

===Apparent death===
[[Image:Cluemast.png|Cluemaster mourning the loss of his daughter. Art by Pete Woods.|thumb|left]]
Cluemaster and his teammates in the Injustice League volunteer to join the second [[Suicide Squad]], a group sanctioned by the US government, in return for a full pardon of his crimes. The Cluemaster also hopes to make Stephanie proud of him.<ref name="dc-ency"/> During the mission, which involves dealing with terrorists and a lovesick genetic experiment, Cluemaster sees his friends, [[Big Sir (character)|Big Sir]], [[Clock King]] and [[Multi-Man]] die (though Multi-Man has the power to be reborn). In the resulting chaotic battle, Cluemaster seemingly saves [[Major Disaster]]'s life twice, though the Major admits the situation was confusing. Cluemaster is seen shot many times through the chest. He survives this incident, with a year's recuperation in the hospital and many, many scars. He is encouraged by thoughts of his daughter.<ref>''Suicide Squad'' (vol. 2) #1 (November 2001): "Almost a Good Idea". DC Comics.</ref>

When he escapes and discovers that his daughter has been killed, he takes on the secret identity Aaron Black and creates the "Campaign for Culpability", blaming Batman for his involvement in Stephanie's death, saying that she was not the first child working with Batman to die, and that Batman should be brought to justice.

It is later revealed that Stephanie survived the incident that everyone believed had killed her, and spent some time recuperating overseas.<ref>''Robin'' (vol. 2) #174 (July 2008). DC Comics.</ref>

''Robin'' (vol. 2) #177 was planned by [[Chuck Dixon]] intended to feature Cluemaster, but Dixon's abrupt exodus from DC meant the issue was scrapped.

Cluemaster finally reappears after Stephanie Brown has become the new [[Batgirl]]. He is revealed to be a sponsor of the Reapers, a group of young supervillains who have been battling Batgirl.<ref>''Batgirl'' (vol. 3) #23 (July 2011). DC Comics.</ref>

===The New 52===
In September 2011, [[The New 52]] rebooted DC's continuity. In this new timeline, as part of the ''[[Forever Evil]]'' storyline, Cluemaster is among the villains that the [[Crime Syndicate of America]] recruited to join the [[Secret Society of Super Villains]].<ref>''Forever Evil'' #1. DC Comics.</ref>

Cluemaster appears as a villain in ''[[Batman: Eternal]]'', plotting with several other minor villains when interrupted by his daughter, Stephanie Brown, who overhears part of the plotting by her father and his associates.  This is Cluemaster's first full appearance in the New 52 continuity.<ref>{{cite web|last1=Lee|first1=Roger|title=Villains in the Batman: Eternal Series|url=http://www.superheroreviews.com/villains-in-the-batman-eternal-series/|website=Superhero Reviews|access-date=8 June 2017|date=April 27, 2014|archive-url=https://web.archive.org/web/20150404121832/http://www.superheroreviews.com/villains-in-the-batman-eternal-series/|archive-date=4 April 2015|url-status=usurped}}</ref> He is later revealed to be the final mastermind behind the systematic attack on Batman by various villains; inspired by an old theory he had when talking with other lower-grade villains that they could take action while Batman was occupied with the bigger criminals, he sent out invitations to other big-league foes to take action after the fall of Commissioner Gordon, and then all he had to do was slip a basic mind-control drug into Gordon's coffee to make him see a threat that wasn't there and let the other villains do what they wanted, guessing correctly that Batman would never think to look at a small-timer when so many bigger villains were playing a part in the scheme. Although Brown manages to capture and unmask Batman, Bruce is able to escape his bonds and fight back, but he has taken such a beating over the course of the storyline that Cluemaster manages to overpower him, only for [[Owlman (character)|Lincoln March]] to show up behind Cluemaster and slit his throat,<ref>''Batman Eternal'' #51. DC Comics.</ref> revealing that he funded Cluemaster's plans solely so that he could kill Batman at this point in secret.<ref>''Batman Eternal'' #52. DC Comics.</ref>

===DC Rebirth===
In 2016, DC Comics implemented a relaunch of its books called "[[DC Rebirth]]" which restored its continuity to a form much as it was prior to "The New 52". During "The War of Jokes and Riddles", Cluemaster is seen as a member of [[Joker (character)|Joker]]'s team.<ref>''Batman'' (vol. 3) #26 (September 2017). DC Comics.</ref> After Batman joins the war on the side of the Riddler and begins taking out Joker’s allies one by one, Cluemaster suggests to [[Kite Man]] that they let themselves be beaten rather than flee and face the wrath of both kingpins. However, he is then gassed by the Scarecrow, one of Riddler’s allies, and taken out of the conflict.

In a three-issue story arc beginning in ''Batgirls'' #13 (February 2023) Cluemaster kidnaps Stephanie but is thwarted by [[Cassandra Cain]].

==Powers and abilities==
Unlike most of Batman's villains, Cluemaster is completely sane, which gives him a unique relationship with Batman. Cluemaster has no [[metahuman]] powers or abilities. He has a number of plasti-glass pellets attached to the front of his uniform. The pellets contain various offensive weaponry including: blinding incendiary flares, smoke, incapacitating gas, and explosives.
