I really like Lord Edgware Dies, the ABC murders, Elephants Can Remember from the ones I've read. A lot of people like The Murder of Roger Ackroyd and Then There Were None. You should try a couple of her books! Not all are as good plot-wise but they're nice to read.

And she's written some non-mysteries too as Mary Westmacott. I really liked Giant's Bread, from those.
