“Everyone at the hospital where Jan Marlowe worked as Librarian was seething with excitement about the new consultant Ophthalmic Surgeon. Jan liked him too, but found one of the patients more attractive still - or did she?”
Hospital Librarian by Margaret Malcolm. This is actually a very rare romance book, first published by Mills & Boon in 1960 and then Harlequin in 1961. The painted cover artwork is by Paul Anna Soik - one of the most prolific designers in the early days of Harlequin.
