Crime City Central, episode 106.
Technically this is the best story I heard last week. I have been enjoying Crime City Central ever since they created a podcast of one of my own stories. And I have read a few of Mr. Leather's novels. but this is my first exposure to his short stories.
And a good one it is, with a bit of a split personality. It is set in Singapore, the "city without crime." An American tourist has been murdered in a hotel and Inspector Zhang calmly works his way through the investigation.
But the whole tone changes when our heroes realizes, with delight, that this is what he has been waiting for his entire career for: a locked room mystery. He becomes more eccentric as he lectures his suspects and fellow officers on John Dickson Carr's famous seven types of locked room murders. And inevitably he comes up with a fair solution that the reader should have seen coming. You won't, of course. But that's part of the fun.
