The Documents in the Case · Chapter
Statement of Paul Harrison [Continued] explained
Paul Harrison continues his statement, detailing his investigation into Lathom's guilt.
What happens
Paul Harrison continues his statement, detailing his investigation into Lathom's guilt. He abandons the idea of checking Lathom's alibi and focuses on the possibility that the poison was added to the beef-stock at The Shack. After recalling a letter from Munting about a laboratory at St. Anthony's, Harrison and Munting visit the labs to see if it would be possible for an outsider to access poisons. They find the labs easily accessible, but Munting points out that proving Lathom stole synthetic muscarine would be nearly impossible, as there is no way to distinguish it from the natural poison. Harrison concludes that Lathom has devised a method of murder that is proof against proof.
