Don't know. Lucius?

Uh. That would be a tad obvious. :-/

A young Sherlock Holmes?

The general idea is correct, but it obviously wouldn't be Holmes (unless it would be some hallucination or time-travelling investigation, which it is not).

It's Hercule, from "Sherlock Holmes: the Awakened".

Uh. Full name ?

Oh wow! Hercule Poirot?

I take no credit, if it's correct BreOl72 can continue the turn.

It's ok...you can take the credit, I botched the answer up.
Besides: I would need to look for some new searchable character first - I have none at hand right now. :)

Yes. That's why I implied that "young ___" was on the right tracks, and that it wasn't necessarily a gaming celebrity.

It's a fun short cameo in that Holmes game. A fleeting encounter during which Watson lectures a kid about "using his little grey cells", before we hear the kid being called Hercule, by a lady named "miss Poirot" (that last hint being a bit of a superfluous removal of subtlety). I wondered if Bre had only stumbled upon the "Hercule" call, and I didn't want to declare a winner without being sure they got the actual identity right.

So, next is.... whoever.

Looks like Nines Rodriguez from V:tM Bloodlines.

You got it right! That's fast...
Your turn.

Meanwhile I'd like to reread my Agatha Christie novels again.

Next:

That should make it easier...
