Death In Paradise

BBC1, 9pm, Thur

Poor Humphrey. He manages to spend a romantic weekend on a remote island with Martha, but it seems murder follows him around like a bad smell.

The break is ruined when a hotel guest is found stabbed to death in his room during what appears to have been a robbery.

However, there are no signs of anyone having broken and entered, so Humphrey becomes convinced that the culprit must have been somebody the victim knew and invited them in.
