Chapter Three: Ipsissimus:
Mycroft invites and hires the Irregulars at the house of the Golden Dawn (an occult cult) when its leader got murdered.
Not bad how this unfolded and what the chapter title means.

Chapter Five: Students of the Unhallowed Arts:
Fascinating the story that Sherlock tells Bea about his life from 15 years before as she wants to know about her mother.

Harrowing for Billy seeing a horrible man from his past.

I have my own version of this man and that is a high school principal as I am haunted by his mistreatment of me.

Chapter Six: Hieracium Snowdoniense:
Not bad the case with the Snowdonia Hawkweed.
Bea sure wasn't happy on being the truth about Leo.
