Nobody remembers the young men entering the abandoned London flat a few weeks ago. Nobody cares if they left.
Until the unbearable smell of decay.
DCI Antonia Hawkins is called in to view the dead men; three, lying neat in a row.
There's no damage to the bodies, no obvious cause of death. Is this a suicide pact? Or is that just how it's meant to look?
If there is a link between the three very different men then Hawkins needs to find it, and fast.
Because unless she does, more are going to die. And they might not all be strangers.
