Moord in de martelstoel

I have been reading through all of Christie's mysteries chronologically and this one didn't impress me much. It is called either One, Two, Buckle My Shoe (UK version) or The Patriotic Murders (US version) but neither title resonated. The politics of it are murky. She doesn't risk going into political specifics (which is understandable) so the motives seemed weak to me. It's not a bad read, especially if you are a diehard Christie fan. But it's not one I would recommend to someone just looking for a good one-off mystery to read.
