Reflecting, Ewan felt a pang of betrayal. He’d always considered Ross his friend. Friends didn’t hide things from one another. Ross’s deliberate act of secrecy smacked of mistrust and deviousness. What did he think, that Ewan would try to steal his precious coins? Claim his share, because they’d been discovered on company time?

But hold on a minute, Ewan thought. This wasn’t making any sense. What were the coins doing lying about in the van in the first place? Who wouldn’t have brought them inside and made sure they were safely hidden away? Which meant, or implied, that the reason Ross had left these two particular coins in the van was that he didn’t know they were there.

Which in turn also meant, or implied, that the reason he didn’t know they were there was that he’d accidentally dropped them, in his typically clumsy and negligent style, while his attention was taken up with something else. And what else could possibly have distracted him in such a way?

One logical answer sprang to mind.

More coins.

Ewan could picture it perfectly. Ross, delirious with greedy joy at his find, scrambling home in such a rush that the gold was literally slipping through his fingers. How many more coins could he have found? Enough, obviously, that he hadn’t bothered even counting them until he got back to his flat, or else he’d surely have missed these two. Dozens of them? Scores? Who could say?

But then Ewan had another thought that made his blood turn cold.

If these two coins represented only a minor fraction of Ross’s haul, as logic suggested, then where were the rest? What if Ross had had them on his person, keeping them close, when the alleged killers struck? What if the killers had taken them?

And worst of all, what if the gold was the reason they’d killed him?

Suddenly this whole dreadful thing made some kind of sense.

Ewan pocketed the pair of coins and pulled out his phone to call his uncle. No reply, and no messaging service on which to leave a voicemail. Ewan only had the Italian landline number to reach him on. He wasn’t even sure if Boonzie possessed a mobile. Knowing him, perhaps not. There was an email address for him and Mirella, but Ewan had given up sending messages to it long ago.

Ewan couldn’t stand passively waiting any longer. He had to do something. People must be told about this. Now there was not only a potential witness to the crime, but a likely and compelling motive to boot.
