We've had a week to digest the shocking assassination of opposition figure Boris Nemtsov, and opinions are hardening about who was behind it and why.
And the way various Kremlin-watchers have interpreted it says a lot about how each views Russia.
Those who see an emerging dictatorship led by a ruthless tyrant tend to see this as a hit ordered by Vladimir Putin's regime. And those who see a fragile, tottering, and fragmented autocracy tend to suspect rogue elements in the security services or nationalists.
But few doubt that such a brazen hit on such a high-profile opposition figure clearly represents a major turning point in Russian politics.
On the latest Power Vertical Podcast, we try to unpack all this.
Joining me is co-host Mark Galeotti, a professor at NYU, an expert on Russia's security services, and author of the blog In Moscow's Shadows; and Sean Guillory of the University of Pittsburgh's Center for Russian and Eastern European Studies, author of Sean's Russia blog, and host of the newly launched SRB Podcast.
