The Mystery of the Twice-Dead Professor!

The Mystery of the Twice-Dead Professor! was a virtual representation of one of Jacob and Evie Frye's genetic memories, relived by a Helix initiate through the Helix Navigator.

Description
Jacob and Evie met with Arthur Conan Doyle and Henry Raymond in the Strand, where they were presented with another murder case.

Dialogue
The Frye twins started their investigation.
 * Henry: Here's an especially exciting one! Perfect for a penny dreadful!
 * Arthur: A famous professor dies twice!
 * Henry: That's once more than usual! Twice as many sales! My name will soon be known across the nation!

Byng's home

 * Emmett (Byng): It's unthinkable. Such a great man. We were still in mourning from the burial! He was buried yesterday in the family plot.
 * Emmett (crate): My father was an eminent anthropologist and something of an explorer. He made his name by investigating the practices of a small village in the Congo. His colleagues at the university often send him trinkets from abroad.
 * Emmett (will): This is no time to talk about the will! It is true that my father and my fiancée didn't get on, but I'm confident that once he got to know her as a daughter-in-law, they would have become friends.
 * Angela (Byng): It's so very awful! The Professor died of a heart attack just days ago. Then tonight I hear poundin' at the door! I open it to find him bleedin' and in pain! He tried to say somethin' then collapsed dead. Again!
 * Angela (crate): He got that a few days ago. Inside was a statue. I thought it was a marvel, but he told me it was quite common. I dunno who sent it.
 * Angela (spider): Spider? Best get that out of here. Emmett is deadly afraid of spiders.
 * Angela (last words): He kept repeating, "bah kesso, bah kesso." Over and over. What does it mean?

Cemetery

 * Beswick (Byng): He showed up again? First time that's happened in thirty-five years of gravediggin'!
 * Beswick (tomb): I saw the son lock the tomb meself.
 * Beswick (money): It's plan that seven guineas is a lot for a bloke like me. I'm careful with me pennies and save for a rainy day.
 * Beswick (grave robbery): Body snatching? That is an insult. I'd be in the slammer quick as that if I got caught.
 * Beswick (body-snatching proven): So I sell a body or two on the side - a man's gotta eat, ain't he? I broke the lock and left him on a barrow just behind his tomb. Was dark, couldn't really see, but some fella come by and carted the ol' professor off. It's muddy back there, you can likely still see the tracks.

University

 * Silas (Byng): The anthropological sciences have lost a great mind. He revolutionized the field. It is my fond hope that I may inherit his mantle.
 * Silas (Byng's book): Which one is that? Sorry, difficult to read. I've lost my spectacles somewhere.
 * Silas (travels): I recently traveled to Africa in order to continue studies on the indigenous tribe Professor Byng discovered some time ago.
 * Wilson (Byng): An eminent colleague. He wrote prolifically - probably no one will ever amass the amount of knowledge he acquired.
 * Wilson (empty box): I'm most vexed about that! A rare specimen of the sort I've been studying for years. It escaped a few days ago, no doubt due to that scatter-brained assistant, Virginia.
 * Wilson (spider): My thesis subject. My South American colleagues tell me that this particular arachnid is only found in the Bolivian Andes. Fascinating subject.
 * Virginia (Byng): A lovely man. And quite wealthy! I only wish he had lived to bless my alliance with his son.
 * Virginia (will): I'm sorry to hear about that. Do you know whether that change was actually made?
 * Virginia (handkerchief): Yes, that's mine. I misplaced a similar one, possibly at the funeral. I was so upset.
 * Virginia (receipt): I hoped you wouldn't find that. I'm afraid several of the faculty purchase cadavers for research purposes. It's a fact of university life.

Byng's home

 * Dead spider - A large distinctive spider, curled up in death.
 * Prof. Byng's body - The body shows evidence of having been in a terrible struggle. There is a deep cut to the forehead that appears to be surgical: the cut goes into the skull itself.
 * Crate - An open wooden crate, shipped from within London. It is clearly marked: "To be opened only by Prof. Byng personally.
 * Sculpture - An intricately carved sculpture evidently of African origin. There is a small recess where something could have been hidden.
 * Personal letter - "My dearest love. I do not understand your father's antipathy towards me. I fear that he will take steps to disrupt our engagement. Please obtain his assurances that, no matter if you marry me or no, he will render you your due when the time comes. - Your betrothed, Virginia"
 * Legal letter - A recent letter to Prof. Byng from his attorney. "My dear Byng, I can certainly amend your will to discourage the marriage of your son with the young lady in question. An annual allowance that will be suspended in the event of such a marriage should serve the purpose. If, as you suspect, she is driven by love of money, such a provision should considerably dampen her ardor for your son."
 * Letter from colleague - "Esteemed Prof. Byng. My research trip has been a great success. I have been able to verify personally several of the unusual customs that you chronicled in your brilliant book. Once again I am humbled by your genius. - Prof. Silas."

Cemetery

 * Byng family vault - The lock is broken. The door is ajar. Prof. Byng's casket is empty.
 * Gravedigger's coat - An old, worn coat. One pocket contains a crumpled note: "Here's the sum agreed upon for last night's transaction."
 * Handkerchief - A lace handkerchief with red embroidery.
 * Money - Seven pounds sterling.

University

 * Treatise by Prof. Wilson - On the topic of an unusual Bolivian spider. One passage notes that the venom "produces a state resembling death" and that "some Andean tribes use the venom during a rite of passage in which initiate boys experience a symbolic death lasting two or three days."
 * Small box - An empty box labeled Arachnid Harpadectus.
 * Spider illustration - An illustration of a spider resembling the dead spider found in the Byng home. A note describes it as a rare spider found in Bolivia whose venom is a strong tranquilizer.

Dialogue
Professor Silas was accused of the murder.
 * Silas: I required his knowledge in order to become the greatest anthropologist in the British Empire! And his beloved tribe of savages provided the method.
 * Arthur: That Professor Silas was particularly cunning and gruesome. Mr. Raymond will be thrilled!
