ARNIE KOTT OWNED THE only harpsichord on Mars. However, it was out of tune, and he could find no one to service it. No matter which way you cut it, there were no harpsichord tuners on Mars. For a month now he had been training his tame Bleekman to tackle this task; Bleekmen had a fine ear for music, and his particular one seemed to understand what Arnie wanted. Heliogabalus had been provided with a translation into the Bleeky dialect of a manual on keyboard instrument maintenance, and Arnie expected results any day now. But meanwhile the harpsichord was virtually unplayable.
