The Fife-born, Edinburgh-based crime writer said he lost his credit card wallet on the top deck of the bus – and has pleaded with anyone who finds it to hand it in to Lothian Buses.
Posting on Twitter, the Inspector Rebus writer said: ‘Any Edinburgh folk using No26 bus today – credit card wallet left on top deck. Please do hand in/report! @on_lothianbuses'.
Last year, the 60-year-old said books featuring his most famous literary creation now “make me a seven-figure sum”.
He also revealed that these days he writes a book every second year, but even in the year he takes off, he still brings in a six-figure sum.
Rankin's most recent Rebus novel, the excellent A Song For The Dark Times, will be released in paperback on April 29.
