April, 2028, and independent Edinburgh is facing a mounting crime wave.

Experts from the utopian university-state of New Oxford recommend an extreme deterrent – a maximum security prison alongside the central tourist zone.

At the prison opening ceremony, the unthinkable happens – an Edinburgh guardian is shot.

Having linked New Oxford to the assassination, maverick investigator Quintilian Dalrymple travels there to close the case.

Once there, he discovers evidence of a ruthless conspiracy extending to his home city and the only way to stop it is to penetrate New Oxford’s mysterious heart – the place known only as the House of Dust.
