The Shadow Friend / Тени теней / Книга на Английском; Penguin, 2020

The victim was your friend

It was just a silly game to start with. Paul never really believed in it.

He never dreamed Charlie would take it so far.

So was the murderer

For twenty years, Paul's tried to put his past behind him, but now his mother is dying, and he can't run any longer.

But home isn't just full of bad memories. It's also the last place anyone saw Charlie alive.

And Paul starts to wonder if Charlie might come back to finish what he started . . .
