I found Someone from the Past to be the best of the British Library Crime Classics I’ve read so far. It has a smart, feisty, occasionally indiscreet heroine, is fast moving, sometimes exciting, and presents an interesting, character-based mystery.
Nancy is at a restaurant about to receive a proposal from her boyfriend Donald when her estranged friend Sarah approaches the table. This approach creates some awkward moments, because Donald was the last in a string of Sarah’s lovers and didn’t take her departure well. Finally, he leaves the table so the women can talk.
Sarah tells Nancy she is about to marry a wealthy man, Charles. Then she says that someone has been writing her letters threatening her life. As Nancy is a reporter and knows all the suspects—Sarah’s discarded boyfriends—Sarah asks her to try to find out who is writing the letters. She says she’ll send her one of them in the morning.
Nancy’s evening ends poorly, with Donald stomping off. But the next morning, he arrives at her flat, confused and frightened. He tells her he went to see Sarah in the early hours of the morning and ended up falling asleep in the sitting room. When he awakened shortly after eight, he found Sarah murdered in her bed. He is sure the police will think he did it.
To protect Donald, Nancy lets herself into Sarah’s apartment and tries to remove all traces of his visit. In doing so, she notices some odd things about the scene. Unfortunately, when the cleaning lady arrives, Nancy puts the chain on the latch instead of hiding or going out another way so it was obvious someone was in the flat.
Shortly after she arrives home, the police are at her door. They think she killed Sarah, partly because she left her own fingerprint in the apartment and because the cleaning lady recognized her when Nancy met one of Sarah’s other lovers in a pub before going home. Nancy thinks the only way to clear herself and Donald is to figure out who did it herself. The list of suspects consists of Sarah’s last four lovers, including Donald.
Nancy finds she isn’t very good at lying to the police, keeping secrets, or fleeing the country, but she is good at figuring out clues. I’m not so sure she’s that good at picking future husbands, though.
I received this book from the publishers in exchange for a free and fair review.

I loved this one too. The atmosphere is kinda noirish, but there’s too much warmth in Nancy’s character for it to be quite as bleak as noir usually is. I was pleased, because I’ve had very mixed feelings about the couple of Bennetts the BL had previously produced.
I think this is my first one.
