Murder is a Tricky Business

There's a secret, that much is certain, but who knows? The missing actress? The executive producer, his eavesdropping assistant? Or the actor who portrayed her fictional brother on the Soap Opera?

DCI Isaac Cook of the Murder Investigation Team at Challis Street Police Station in London is searching for the missing woman.
