September 11th — 12th, 1927
After a sleepless night, the four rose on Sunday and headed to morning church. After mass, Narendera Bose and Kang Leong headed back to Lyle Street while Father Xavier and William Keen investigated the police station for leads about Amy Cooper’s mysterious death.
On Lyle Street, Bose and Leong talked to some sewer-workers who were pumping from a basement at number 1412. Upon investigation of the basement they discovered (thanks to Leong’s powerful head) beneath the cracked wet flooring a hidden room.
William Keen and Father Xavier did not gain much information from the police, but they had more luck elsewhere. William Keen discovered that Miss Cooper had stayed at the Baronial Arms in Salem. In the room, Keen discovered a crumpled piece of paper which read Mercy Booth, 1412L. Xavier and Keen hurried to Lyle Street.
The four were re-united at 1412 Lyle Street, but they realised that they would need more equipment to investigate the room below (it being Sunday, all of the shops were closed). Instead, they returned to Fairfax Cemetery. There they found a large burrow or hole near the Crawford Mausoleum. Kwang and Father investigated. The hole led to a tunnel which extended beneath the cemetery but lack of light and the tunnel’s queer stench caused the pair to retreat. All four returned to the hotel for the night.
On Monday, after properly equipping themselves, the investigators returned to Lyle Street. Narendera Bose was lowered into the chamber. Strange mosaics covered the walls. The floor was awash with raw sewerage. Father Xavier, his interest piqued by Bose’s description, was eager investigate. The pair found a large iron disk beneath the water. While Bose examined the disk, Xavier spotted a concealed door and pushed it open. Beyond the door was a small stone room. Seated at a table was an unmoving figure in a brown robe. Closer investigation revealed the figure to be a hideous mummified corpse. The corpse clutched a black book which Father Xavier did so. As he did so, the corpse shot bolt upright and reached for him with its claws.
Father Xavier fled for the door as an awful gurgling chant came from the corpse’s deformed lips. Narendera Bose cool-headedly opened fire with a shotgun, but as he did so his skin shrivelled and blackened and he fell to the ground senseless. Father Xavier fearfully groped for his pistol and fired off a couple of shots at the thing, even as he felt his own skin begin to burn with pain.
Hearing the screams from below, Kwang Leong shimmied down the rope and ran towards the concealed room. A gruesome sight greeted him. Bose had collapsed and Father Xavier gazed sightlessly forward, babbling insanely and clutching his black book and gun. The corpse had been destroyed, and lay still, but Leong shuddered as he saw a shimmering blue irridescence rise from the body and float towards the far wall, where it slowly faded.
Keen and Leong bandaged up their wounded comrades as best they could. Xavier had ceased his babbling and now stared vacantly forward, though he still refused to relinquish his gun or book. Keen found a scroll which described Mercy Booth’s infernal deal with the ghouls. The four left the dark chamber and returned to Boston, somewhat the worse for their strange experience. In the weeks that followed, Narendera slowly regained his strength and Father Xavier regained his senses.
Suspecting that something of Mercy Booth remained, William Keen studied her journal (the black book which Father Xavier had recovered) intently. It contained many disturbing hints about the worship of dark Nygotha, including instructions on how to construct a mystic gate to another world. He realised that the wall of her chamber was one of these gates. He returned to Salem with Bose and Leong in order to destroy it. When they arrived at the hidden chamber they found that the gate had already been closed – from the other side. The witch Mercy Booth was gone, but Mr Keen and his friends would never be the same again.
