Measured over 1 original post from a 30-day window, last computed on August 26, 2026.
Engagement
Early reading. We have captured 1 original post for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 87 interactions against 1.6M followers, an engagement rate of 0.005%. Posts are seen about 18K times each, and 0.474% of those impressions turn into an interaction. That is about 1.14% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.07 posts a day over the last 30 days, though only 3% of days saw any activity at all. Most posts go out around 09:00 UTC, and Tuesday is the busiest day of the week. Of the 1 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 450 interactions, about 5.2x its own typical post. Only 1 original post have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 09:00 UTC, and Tuesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Last night we were thrilled to host an event celebrating one of Agatha Christie’s finest novels, The Seven Dials Mystery from 1929, to celebrate its upcoming @NetflixUK adaptation. To talk about the making of this hotly-anticipated release, we welcomed cast members Mia McKenna Bruce, Helena Bonham Carter and Martin Freeman, director and executive producer Chris Sweeney and writer and executive producer Chris Chibnall. This discussion was particularly special, ahead of our own major exhibition exploring the life and works of Agatha Christie in autumn 2026. We’re thrilled to be partnering with Netflix on these exciting literary conversations, continuing the momentum from our recent events with the director and cast of The Thursday Murder Club and Frankenstein.
