My first Sherlock fan-fic, and my first texting fan-fic. Seems appropriate. I hope I have gotten the characterizations right. I may have veered too much into literary Sherlock characterization, 1800s (Or film portrayals of literary Sherlock) but I think it's close.
Hudson: Hello, Sherlock.
SH: Hello, Mrs. H.
Hudson: How are you?
SH: Well.
Hudson: That's nice.
SH: Ah, yes, I forget, how are you?
Hudson: I'm fine as well, just a bit tired. Been busy?
SH: Quite.
Hudson: That's nice.
SH: Well?
Hudson: Well what?
SH: You are texting me. Why?
Hudson: I'm in London.
SH: Visiting or staying?
Hudson: Staying, I think. I'm looking.
SH: What for?
Hudson: I would like to own a townhouse here in London, but they're so expensive.
SH: You could convert it into a flat.
Hudson: A flat? Me, a landlady? Imagine that. I'm not sure.
SH: You could be a fine landlady.
Hudson: Might not be so bad, I suppose. I would be in charge of collecting rent, and things like that.
SH: You could be the finest landlady in all the world.
Hudson: Sherlock, you tease.
SH: I'm not joking, I believe you could be.
Hudson: Thank you.
SH: Of course, you would have to be careful.
Hudson: Careful of what?
SH: Your tenants. They could be devious. Deviants even.
Hudson: I'm not sure I would mind too much, as long as they are not loud and pay the rent on time.
SH: Good to hear.
Hudson: Are you interested?
SH: I'm glad you asked, Mrs. H. Yes.
Hudson: I hope you can afford to pay the rent.
SH: I will try my best.
Hudson: I will be stiff. And the rent may be high for you.
SH: I expect that.
Hudson: You may have to take on a roommate.
SH: No. No no no no.
Hudson: It may come to that.
SH: I hope it does not come to that.
Hudson: What's so wrong with having a roommate?
SH: A roommate will disturb my affairs, Mrs. H. I cannot abide that!
Hudson: A roommate could be fun.
SH: Ha.
Hudson: Sherlock, please consider it. I have my eye on an already converted flat in Baker Street.
SH: 221?
Hudson: How do you know?
SH: Mrs. H.
Hudson: Right, sorry.
SH: Looking at the listing. Seems reasonable.
Hudson: It will take some money to repair.
SH: Right. Price goes up.
Hudson: Sherlock, will you please consider a roommate?
SH: All right, I will. I will have to go find one.
Hudson: Take your time. Purchase has to be finalized, and then the place has to be repaired. This will take weeks.
SH: I am patient, Mrs. H. I will have to go find myself a good roommate in the meanwhile. Which apartment?
Hudson: 221B is best. 221C is damp.
SH: 221B Baker Street, you are mine. And my eventual roommate's. See you soon, Mrs. H.
Hudson: See you soon, Sherlock.
I hope you liked it. Not sure if I will continue this story. I may do a Doctor Who/Sherlock crossover-ha. Slightly inspired by Moffat's remarks that it would be very awkward for the Doctor and Sherlock to meet.
