Detective Bowie

Detective Bowie is the former codename of a minor supporting character in the Faces, Strange and Secret creepypasta Tick Tock Goes the Clock. He was a member of an unnamed organization that operated from the founding of the Pinkertons in 1850 until the events of the story in June of 1855. The organization he worked for frequently claimed its members were Pinkerton Detectives until shortly before the founding of the SMSC. This, along with their similar objectives and procedures, has lead to rumors that this organization was the same group as or a precursor to the SMSC, which has been denied by all SMSC members who have replied to the question.

Tick Tock Goes the Clock
On June 29th, 1855, Bowie was on a mission to locate the Manufactured Newborn on a passenger train before it could assimilate more people when he recognized a gang of bank robbers. He promised not to turn them in so long as they helped him search the train compartment for the Newborn in its mechanical spider form. However, it had grown significantly larger since the last time he saw it and quickly killed off each passenger. All of their attempts to destroy the Newborn by shooting its body only served to make it even stronger, leading to Bowie being horrifically murdered and absorbed onto the Newborn's back so it could watch what was behind it. Once it acquired enough mass, the Newborn took control of the train and diverted it into a portal to The Towering Realm. The only survivor of this event was Emmaus Williams, an outlaw that went on a killing spree in the New Mexico town Devil's Fork after he was transformed into a Towerborn by a pocketwatch he stole from a train conductor.
