Batman: Scarecrow's Panic Plot (Comic Chapter Books)

The mad psychologist is on the loose! Now the Scarecrow has fitted the Dark Knight with a helmet that slowly gives him fear gas as part of a twisted experiment. Batman has no choice but to play along -- the mask is tamper-proof and if he tries to remove it, hell get a toxic dose of the nightmare-inducing fumes! Will Batman outsmart the crazed villain, or will he be driven bat-bonkers?
