I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
Hercule Poirot is involved in a little mystery through his secretary's sister.
It all looks quite harmless, if a bit mischievious, in the beginning.
And then the bodies start to drop :-)
I just love the writing - the way the reader is invited to solve the crime along with M. Poirot.
