The Debt was the worst thing to have come into my life. It had almost killed me about a dozen times in a dozen different ways. But here I was wanting, willing, it to contact me. To give me the next instalment.

After Rome, Dom has quit running. He's still training, though. Swimming lap after lap of the pool. And waiting.

Until Dom receives another threatening message. In Latin. He doesn't know who is after him now, but he hopes it's The Debt. He's pieced together the puzzle of the previous instalments, and he knows that the fifth one must be the search for Yamashita's Gold - the legendary treasure looted during the Second World War that might have ended up in the waters of Diablo Bay.

But for months he's heard nothing from The Debt. Just silence and more silence from this shadowy organisation. Could this message be it?

But if Dom goes out searching, he won't be the only one looking for gold. And The Debt won't be the only organisation looking for Dom. It might be desperate times, desperate measures, but there's only one person looking out for Dom Silvagni - himself.
