The rarest postage stamps, the fabled Plate 77 Penny Reds, are at the heart of the latest Detective Dan Calder crime novel by Ian Austin.
You can throw in a terrorist bombing plot at Auckland Airport, a photograph that's been torn in two and Dan's chaotic family life into the mix.
Ian Austin is a former detective himself so he clearly knows what he's writing about. Bonded is the fourth novel featuring Calder, and he tells Lynn Freeman that it was inspired by a real story "almost too amazing to be true."
Bonded is published by I.A. Books.
