The Corner Shop — Elizabeth Cadell

Tomorrow Lucille Abbey was supposed to be in romantic Paris with the handsome, correct London stockbroker who had asked her to be his wife. But at the last moment she had to fly to the huge country home of Professor Hallam to straighten out a tangled business problem.

By the time she got to Paris, the Professor's strange life had changed her own, and the romantic trip with her fiance turned into a nightmare of intrigue and suspense. Love was around the strange and shadowy corner in the dusty Paris quarter, too.
