Lots of delayed follow-ups to Stephen Brook's Media Guardian scoop on Thursday about the disappearance of the City AM co-founder Leonid Rozhetskin. It took most papers a couple of days to realise the story's importance.
Rozhetskin, a Russian-born businessman vanished from his holiday home in Latvia eight days ago. Police found bloodstains, broken furniture and smashed windows. Two days previously he had met City AM executives in London. He is a major shareholder in a Dutch consortium that owns 50% of the free paper.
Rozhetskin, aged 41, was previously executive vice chairman of Norilsk Nickel, Russia's largest mining company. In 2006, according to a Daily Telegraph story, Russian prosecutors placed him on a wanted list for an alleged £20m fraud. He has also been regarded as a critic of Russia's president, Vladimir Putin.
The story gained extra legs today with a splash and a spread in the Mail on Sunday, which claimed that Rozhetskin's disappearance may be linked to the murder of former KGB spy Alexander Litvinenko, who died from radiation poisoning in London in November 2006.
To that end, the Latvian police have contacted Scotland Yard, but it appears to be only one line of inquiry. A further mystery is that Rozhetskin's private jet vanished for 48 hours until it turned up unexpectedly in Zurich, without any passengers aboard.
The fact that it managed to obtain air traffic clearance to leave Latvia, without police knowledge, has tended to bolster the theory of a secret service conspiracy. Meanwhile, Rozhetskin - described by the MoS as a "jet-setting billionaire" - is still missing.
