A mild, readable little mystery that has narrator Lucy and her smart friend Susannah, a judge's granddaughter and a would-be detective, snooping around at night in the large but rundown house of a recently deceased, once-wealthy old man. The snooping is on behalf of classmate Juliet, a shy girl with a bad scar who had been close to the old man. He had promised to leave her something in his will, and now Lucy and Susannah search for a will and for the unspecified ""treasure"" he had mentioned. There are the usual bumps and creaks in the dark--someone else appears to be searching for the treasure--but Susannah's sharp eyes and wits find it for Juliet, who can now afford an operation to remove her scar. (Incidentally, even arbitrarily, Susannah is colored black.) Inconsequential but agreeable.
