Don’t dream of not bringing the kids for this whodunit in which, we are told, the whole orchestra is a suspect. Text by Lemony Snicket, whose cyanide whimsy verbal children adore. Music by Nathaniel Stookey, as yet unknown to us. Can he compete with Sergei (Peter and the Wolf) Prokofiev? Benjamin (A Young Person’s Guide to the Orchestra) Britten? Raphael (The Travels of Babar) Mostel, son of Zero? Here’s hoping he can. —M.G.
