Wiseman listens raptly as a panoply of docents decode the great canvases of Da Vinci, Rembrandt, and Turner; he visits with the museum's restorers as they use magnifying
glasses, tiny eye -
droppers, scalpels, and Q - tips to repair an infinitesimal chip; he attends administrative meetings in
which senior executives do (polite) battle with younger ones who want the museum to become less stodgy and more welcoming to a larger cross-section of the public.
