Brad Strickland, writing at the Compleat Bellairs:
The new jacket cover for The Whistle, the Grave and the Ghost is very nice. I think this one is a lot of fun - we see Lewis again bedeviled by bullies, except now that he's older and maybe a little smarter, things don't quite work out the way the bullies expect. And there's a glimpse of one of Lewis's gloomy aunts as well. Won't give away too much, though.
