Okay, I will freely admit I'm rather short on plot bunnies (and B words) - so feel free please to suggest ideas for this series to continue. Many thanks!
"Doctor. I believe I've made a blunder."
"I am rather inclined to agree with you."
"Yes, I thought you might."
Silence. Then…
"What kind of an investigator are you anyway?"
"Well how was I to know –"
"You're supposed to know everything, by your own admission, Holmes!"
"Yes, well, no man is omniscient!"
"Especially you, it seems."
"Oh, do be quiet."
There was a strained silence for a few more minutes.
"You didn't have to come along, you know, Doctor."
"I'm rather wishing I hadn't, actually."
"So am I," I muttered, filled with a genuine guilt.
He sighed quietly.
"Does this sort of thing happen much during your cases, Holmes?"
"With…fair regularity."
"Wonderful. How have you survived for – how many years have you been doing this?"
"Only three. I regret dragging you into it, though."
"It wasn't totally your fault. I'm a soldier, used to stealth tactics – why didn't I see them?"
I was astonished at my new friend's willingness to accept blame for something that was definitely not his fault. But I had no time to think upon the matter; we could hear footsteps nearing our prison.
"Well, at least Lestrade should have your message by now," he said hopefully.
"Er, Doctor? I…forgot…to send the message before we left Baker Street."
"You – forgot."
"As I said, a blunder."
