T-Rex: Sherlock Holmes, who was the world's greatest detective but also mortal, deduced he was going to die some day.

T-Rex: And he further deduced that was going to suck big juicy eggs!

T-Rex: "As I have often solved ALLEGEDLY-insoluble crimes, after my death, there will be many crimes going unsolved again," he deduced. And that, he deduced, was intolerable. Insufferable. It would - quite literally - be a crime, perhaps the world's greatest. And so he did what he always did:
T-Rex: He set out to SOLVE IT.

Utahraptor: Oh snap. Sherlock Holmes is solving IMMORTALITY??
T-Rex: What? NO. Don't be crazy.

Utahraptor: Ah, I see. Sherlock Holmes is having a lot of unprotected sex, so he'll have a lot of kids and hopefully one of 'em will be as good at deduction as he is!
T-Rex: Again, no. Sherlock Holmes is simply opening the world's first detective school. God!

T-Rex: Though I gotta say, your phrase "Sherlock Holmes is having a lot of unprotected sex" would be an AMAZING first line for a story!
Off panel: Or a final one.
T-Rex: Put "Meanwhile," at the top and it has such raw power it could be dropped into even a non-Sherlock story??
