Fourth book in the Russell Quant Mystery series. Creepier and darker than the first three. The main story deals with people from a choir being harassed and ultimately killed by a mystery boogeyman. Russell follows the clues as the killer becomes more and more bold and dangerous. That plot is interesting and Russell shines throughout resolution. It's also creepy, dark and doesn't end all in roses and joy. The secondary plot wraps up the whole Seerena's disappearance. It's a little boring and predictable with two minor twists one I hope we will see again. Overall an entertaining addition to the series. More like 3 1/2 stars
