On this edition of ST, we present another installment in our Museum Confidential podcast series , which is a popular co-production of Public Radio Tulsa and Philbrook Museum of Art. This time out, MC speaks with longtime NYC-museum veteran Christine Coulson, who worked at The Met for a quarter of a century in a variety of roles. She left a couple of years ago to write full-time, and now comes her widely acclaimed and rather experimental debut novel: "Metropolitan Stories."
