I suggest that you read teh early 'Saint' books by Leslie Charteris. They are set in and around London in the 1920s.
The Saint meets the Tiger
Enter the Saint
The Saint Closes the Case
The Avenging Saint
Featuring the Saint
Alias the Saint
The Saint Meets His Match
The Saint v. Scotland Yard
The Saint's Getaway
The Saint and Mr. Teal
The Brighter Buccaneer
The Misfortunes of Mr Teal / The Saint in London
Later books in teh series have a definite setting in the 30s, 40s, and the 50s, in Europe, America, or South America. A couple of those early ones ought to suit you.
The Saint series used to be an amazingly popular best-seller. You ought to find some of those booksin a public library.
