A summary of events:

Jonah sends his latest fine group of investigators to look into what’s going on in a mysterious house, informally known as the “Corbitt House,” in Boston:

• Anastasia, the Amerussian who totally isn’t a spy, and one of the few surviving members of the Dead Light episode
• Sloppy Joe, a boxer who has lost every fight (including against his mother), but apparently has never taken a punch to the ear
• Leonard, a bum who somehow found his way into Jonah’s employment
• Gertrude, an ambitious 16 year old girl

The house apparently has been the source of a couple violent events in the past. In an effort to learn more, they split up to do some research.

Sloppy Joe and Leonard head to the “libary” to look up previous articles about the house. This ends abruptly when Sloppy Joe gets into a fight with an old, fat librarian who lost money betting on him. Sloppy Joe keeps his losing streak alive, and they are both tossed out of the library.

Gertrude and Anastasia head to the Hall of Records and without much trouble find some information suggesting that the Corbitt House’s original owner, Walter Corbitt, might have links to a “Church of Contemplation” that apparently ran into some legal trouble.

The group reconvenes then switches pairs; Anastasia and Leonard head to investigate the church while Sloppy Joe and Gertrude (disguised as a young boy now, for reasons unknown to all) head to the police station to investigate the Church’s legal issues.

Anastasia and Leonard discover the church is long-abandoned, but they do discover a weird “eye” symbol on the church. Anastasia falls through rotting floorboards but lands with catlike agility. She finds a strange latin book, a couple of long-deceased corpses, and a creepy journal that suggests Corbitt was involved in some weird stuff. Leonard steals a ladder to get her out.

At the police station, Sloppy Joe and Gertrude speak to Lt. Martin Poole, a recent transfer to Boston from the NYPD. He had moved from NY to get away from weird stuff that had been happening there over the last half a year. Unfortunately Sloppy Joe and Gertrude do not make his life any easier. He tracks down a redacted police report suggesting something horrible happened during a police raid on the chapel, as well as a court dockett suggesting all arrested church members were released through shady help of a local councilman.

Stalling as much as possible, the entire group heads to the Roxbury Sanatorium, hoping to speak to people involved in the church raid. Instead they speak to someone recently involved in a violent episode in the Corbitt house, who gives them some advice that wasn’t really intended to be meaningful while clutching a bible. The investigators take this as gospel.

They finally head to the house at night time, because that seems the most logical. Leonard brings his stolen ladder.

They enter the house and explore room by room, encountering increasingly strange phenomena: doors that open or close when they’re not looking, fresh and rotten food on the table that appears to be consumed when they’re not in the room, noises with no trace, a bathtub faucet that drains blood momentarily, and a strange book detailing occult experiments and some sort of chant that for some reason none of the investigators try to say out loud.

While investigating an upstairs bedroom, Leonard opens up a door to the balcony. This apparently angers the bed and bedframe, which fly across the room to knock him over the balcony and down to the ground far below. Sloppy Joe destroys the bed frame while Gertrude helps Leonard to his feet.

Anastasia, possibly cranky because she had intended to sleep in that bed, runs down to the basement to investigate a noise she hears. Sloppy Joe follows, and they sift through the junk in the basement. Sloppy Joe spots a knife. The knife spots Sloppy Joe, and flies through the air to attack him. Gertrude, showing up just in time, uses a wooden board to impale the knife and prevent it from tinkerbelling its way into their bodies any further.

Searching the basement Sloppy Joe finds that one of the wooden-planked walls hides a crawl space. After allowing the rats in it to flee, he enters, and emerges into a large adjacent room that appears to contain the dead body of Mr. Corbitt. Anastasia and Gertrude are not terribly interested in joining him. Leonard is outside the house, possibly urinating.

Sloppy Joe inspects the gross, mummifying body of Corbitt while holding the knife embedded in the board over the corpse. Corbitt apparently finds this rude, opens his undead eyes, and grabs onto Sloppy Joe’s wrist. Sloppy Joe screeches and slaps the board-knife down. Corbitt doesn’t seem to care and gets up unnaturally.

Gertrude and Anastasia crawl through to help, emerging to find Sloppy Joe now finding a way to lose a boxing match against a dead guy. Corbitt whispers a few words and Sloppy Joe finds a new purpose in life, grabbing the knife out of the board and running at the 16 year old girl crawling out of the crawlspace. He slashes her, and she falls to the ground with a gaping wound. Covered in Gertrude’s blood, the knife stops believing it can fly.

Anastasia attempts furiously to save Gertrude’s life, which she barely manages to do. Sloppy Joe continues to get into a boxing/knife sparring match with Corbitt, as Leonard finally enters the area with his flaming torch. He throws it at Sloppy Joe. He probably meant to throw it at Corbitt. But he throws it at Sloppy Joe, who has his hair light on fire.

Delirious from being scratched by Corbitt’s claw-like fingernails, and on fire, Sloppy Joe collapses to the ground as Gertrude and Anastasia attempt to throw a switch blade and shoot a bullet at Corbitt respectively. Both miss. Leonard decides to apologize to Sloppy Joe by smothering the fire engulfing him with the blanket Corbitt’s dead body had been lying on top of for dozens of years.

Anastasia, realizing just how far past her bedtime it is, grabs the formerly-floating knife and runs at Corbitt, stabbing him. In a fit of complete coincidence that in no way was planned but somehow worked out regardless, Corbitt’s own weapon pierces and kills him, crumbling his body and the knife into ash. As Anastasia drops the hilt, the house appears to be restore itself to normal. The investigators slowly leave the house, somehow alive to die another day.
