Window of opportunity . . .   Most housecleaners don’t do windows, but Tallie Graver loves leaving a pane of glass streak-free and sparkling. After a dirty divorce from a filthy-rich jerk, she's started her own cleaning business to make ends meet. On her latest job, prepping a renovated bed and breakfast for a grand re-opening, she's standing outside on a ladder, wiping off a grimy pane, when she spies a man on a bed through the glass. But the B&B isn't open for business yet—and the man's not sleeping. Her family owns the Graver Funeral Home, so Tallie knows a corpse when she sees one.   The victim is a shady building inspector with a reputation for handing out passing grades for a greased palm. With the local police resistant, Tallie launches her own investigation, before she gets a rep as a town crank. But it's going to take more than a squirt bottle and a squeegee to clean up this mess. With the help of her gal pal Gina, Tallie searches for a killer's motive. But she'd better be careful, or it'll be curtains for this window cleaner . . .   “An amusing new series with an engaging, spirited sleuth.” —Library Journal
