When the Australian Mystery Writers' Society invites six authors to a festival aboard the Ghan - the famous Darwin to Adelaide train - it's a who's who of crime writing royalty. And me! (The lowly debut author.)

But when one of us is murdered, six authors must become five detectives. This should be easy. Aren't we all experts in whodunnits?

Unfortunately, that also makes us experts in how to commit murder. And, when there's been one, another's sure to follow.

Someone has to solve the case. But can I really outsmart the experts, and catch the killer?
