The Black Cabinet - Patricia Wentworth

Danger lurks round every corner!

Not a murder mystery, but a pacy, exciting story of love and blackmail. The orphaned heiress works as a dressmaker, unaware that she is being watched and considered as the successor to nefarious deeds. Will she escape? Who can she trust? Two would-be suitors, one of them a wrong 'un, but which one? I loved this Golden Age mystery. (Caron Allan)
