You've never met anyone like her . . .

Antonia Scott is special.

Very special. She is not a policewoman or a lawyer. She has never wielded a weapon or carried a badge, and yet, she has solved dozens of crimes.

But it's been a while since Antonia left her attic in Madrid. The things she has lost are much more important to her than the things awaiting her outside. She also doesn't receive visitors.

That's why she really, really doesn't like it when she hears unknown footsteps coming up the stairs. Whoever it is, Antonia is sure that they are coming to look for her. And she likes that even less . . .
