Finding out Janssen was 21 when she wrote her novel has sort of skewed the way I'm reading her novel. It made certain scenes in the book make so much sense on a "Ah...yes, I probably thought the same when I was 21" sort of way rather than a "It works for the plot" sort of way. It sounds ageist and I could very well be completely wrong. I'll do a final objective assessment when I'm done.

Having now watched Sherlock Series 1 a ridiculous number of times, I think I like all three actors' performance about equally, though I'd say Martin Freeman surprised me the most as I'd never seen him do a dramatic role until this one.
