It was a small cage, formerly inhabited by a panther who had regrettably died before his time. The enterprising owner had done his best to furnish it for the occasion, something of a problem, for this Steppenwolf was undoubtedly a rather unusual animal. Just as our friends and lawyers and industrialists allegedly have a wolf concealed beneath their shirts and frock coats, so in his hairy breast this wolf allegedly concealed a complex human soul, Mozart arias, and so on.
