Imagine you found a key. A key that opened a locker. A locker that contained a holdall. A holdall that contained money. A lot of money. £350,000 to be exact. In used, untraceable notes.

What would you do?

Put it back in the locker and walk away?

Contact the police?

Or take it?

It is a life-changing sum.

But what if that money belonged to a dangerous man?

A man that will stop at nothing to get it back.

He will relentlessly track you down and anybody who gets in his way will suffer.

This is what happens when the worlds of three men clash.

Ronnie Moon, Tommy Scott and Adam Lucas are all involved in a deadly game of cat and mouse.

Each wanting the money for different reasons.

The hunt is on and who will survive?

Their greed and ambition could just be The Key to Murder.

'If you want to know what man is really like, take notice of how he behaves when he loses money.'

A pacy, urban thriller with many twists and turns. A clever game of cat and mouse begins were greed and conscience battle each other with deadly consequences.
