'I KNOW IT WAS MURDER - PLEASE HELP ME PROVE IT!'

The Duke of Chellingworth's beloved butler is grieving his brother's death...but was it a really a tragic accident, or was it - as the man's widow believes - murder? Mavis and the dowager Althea offer the services of the WISE Enquiries Agency to investigate, which puts one of their team in a dangerous situation. Meanwhile, Annie and Tudor are puzzled by a spate of petty thefts at their new pub, and Alexander must confront his largely secret past - possibly endangering his new persona and his relationship with Christine...who has a secret of her own. All this while Carol heads up a case involving an aged business tycoon who's desperate to find the Welsh farming family who took him in when he was evacuated from London during World War Two.

It's July in Wales...however, there's no break in sight for our four softly poached PIs, who are not only facing challenging cases, but also juggling complicated personal lives.
