A Body in the Attic

Attics can be full of surprises.  Who could have murdered Darren Powell? He was a very pleasant man fond of puttering around in his garden and playing chess. He didn't seem at all the type of person who'd find himself murdered in his own attic. Myrtle and her senior sidekick Miles step in to investigate. The more they learn about Darren, the more interesting he becomes. And now someone else might be in danger. Can they learn the killer's identity before he strikes again?
