Lya told Inspector Barrington almost the entire story about Jackson Elias and the Ju-Ju House (with the exception of the grave-robbing and unauthorized perusal of Roger Carlyle's files), emphasizing the cult murders.  He seemed very interested and asked her if she was willing to work with the Metropolitan Police.  When she agreed, Barrington told her the following information.  Jackson Elias had been convinced that the murders in London were the work of a cult known as the Brotherhood of the Black Pharaoh.  The victims had all been killed in the same way:  beaten severely and then stabbed through the heart.  Lya said that this was different from the victims in New York but that cult involvement seemed very likely in both cases.

Barrington gave Lya a list detailing the dates and locations that bodies had been found.  He was convinced that there had been more than 14 murders but that the bodies had not been found - sunk in the Thames or dismembered beyond recognition by locomotives.  In one of the cases, the police had found the victim still barely alive, in a large canvas sack on Limehouse docks.  The sack had been weighted with lead, and the perpetrators had no doubt been frightened away by the police before they could toss the sack into the river.  The victim managed to mutter the word 'hotep" before expiring.  According to an Egyptologist, "hotep" was a word in the ancient Egyptian language that meant "peace" or "rest".

Several of the victims had been last seen alive at an Egyptian nightclub in Soho called the Blue Pyramid.  Police plainclothesmen had staked out the place several times but to no avail.  "No doubt they were rather conspicuous".  Barrington asked Lya if she and her associates could visit the Blue Pyramid and see if anything was happening there.  A group of rich and befuddled Americans would not seem at all unusual and might result in some worthwhile information.

Despite the danger, Lya agreed.  Barrington asked her to keep everything he had told her confidential until the case was solved.  Lya gave Barrington Alisa's card and told him that he could contact her via Alisa at Brown's hotel until her new hotel was determined.  She also showed him the framed photogrpah of the Carlisle expedition and asked if he recognized the Negro woman.  Barrington could not but did recognoze Sir Aubrey Penhew.
