Madhu (mathumathik)

In the second row was a boy named Doon Harrow. He sat with his shoulders hunched, his eyes squeezed shut in concentration, and his hands clasped tightly together. His hair looked rumpled, as if he hadn't combed it for a while. He had dark, thick eyebrows, which made him look serious at the best of times and, when he was anxious or angry, came together to form a straight line across his forehead. His brown corduroy jacket was so old that its ridges had flattened out.
