As plain-clothes men go Dangerous Davies looks like a non-starter. The small fry of petty larceny & minor disturbances in the backwaters of north-west London are his daily round. His philosophising Welsh drinking companion Mod his outsized & unruly dog Kitty his quarrels with his landlady Mrs Fulljames
- none of these bodes well for the efficient solving of crimes & the outwitting of villainy. But Davies is encouraged by his beautiful friend Jemma & every so often he stumbles upon something really big.
