— Franken, "One Watson, One Holmes"

Petros Franken, aka "Sucking Chest Wound", is a cyber-activist who is a key member of the hacker collective "Everyone."


Season 3[]

At the Brownstone, Holmes trains himself to mimic death until interrupted by an Everyone member who identifies himself as "Sucking Chest Wound." Holmes won't allow him to enter until he stops chewing gum, so "Chest Wound" puts the gum in a piece of paper. He taunts Holmes by reminding him of the embarrassing things he's made Holmes do in return for Everyone's help. He then indicates that there's in-fighting at Everyone and he wants Holmes' help in identifying "Species", head of a rival faction. Holmes isn't interested and leaves to accompany Watson to a local library. Detective Bell beckons him to a murder scene where he finds that Everyone member Errol White, aka "Species" has been stabbed with a wakizashi. Under White's body, Holmes finds a dyed hair that matches "Chest Wound's." At the Brownstone, reviewing footage from the front door cameras, Holmes finds that "Chest Wound" threw the paper with the gum into a trash can.

I'm sort of important.
Retrieving the paper, they find a set list from a concert is written on it. In the basement, Holmes plays music for Clyde and tells Watson that he found where the set list was played and that "Chest Wound" is a sound engineer named Petros Franken. At the 11th Precinct, Franken fervently denies killing White even when told his hair was found at the scene and various threatening emails he sent to White have been found. He provides an alibi, that he was with investment banker Rachel Carter. At Rachel's office, while she denies being with Franken when White was killed, Bell receives a text that blood matching White's was found in Franken's car trunk. Later, Rachel appears at the Brownstone and admits she was with Franken when White was killed. In the holding cells at the precinct, Holmes tells Franken about Rachel's confession which isn't enough to secure his release.

That's motive, right? Follow the money.
Asking who would benefit from White's death, Franken mentions that White bragged to Everyone's "inner sanctum" about a stash of data worth millions. Finding that the Species account was used by White and another user named "Tessee", who wants Everyone to avenge White's death by executing "Operation Right Nut." Believing that Tessee killed White in order to incite approval of the operation, they visit Franken who is now at Newgate. He doesn't know who "Tessee" is but says that the operation is a hack on the Atherton Foundation.[1]

Tessee's always been a little edgy.
