He heard a shriek, unfamiliar, unearthly.

Not Chuck's, but his own.

Dr. Abby DiMatteo was tired, more tired than she'd ever been in her life. She had been awake for thirty straight hours, if one didn't count her ten-minute nap in the X-ray lounge, and she knew her exhaustion showed. While washing her hands in the SICU sink, she had glimpsed herself in the mirror and had been dismayed by the smudges of fatigue under her dark eyes, by the disarray of her hair, which now hung in a tangled black mane. It was already 10 a.m., and she had not yet showered or even brushed her teeth. Breakfast had been a hardboiled egg and a cup of sweet coffee, handed to her an hour ago by a thoughtful surgical ICU nurse. Abby would be lucky to find time for lunch, luckier still to get out of the hospital by five and home by six. Just to sink into a chair right now would be luxury.

But one did not sit during Monday morning attending rounds. Certainly not when the attending was Dr. ColinWettig, Chairman of Bayside Hospital's Surgical Residency Programme. A retired Army general, Dr. Wetrig had a reputation for crisp and merciless questions. Abby was terrified of the General. So were all the other surgical residents.

Eleven residents now stood in the SICU, forming a semicircle of white coats and green scrub suits. Their gazes were all trained on the residency chairman. They knew that any one of them could be ambushed with a question. To be caught without an answer was to be subjected to a prolonged session of personalized humiliation.

The group had already rounded on four post-op patients, had discussed treatment plans and prognoses. Now they stood assembled beside SICU Bed 11. Abby's new admission. It was her turn to present the case.

Though she held a clipboard in her arms, she did not refer to her notes. She presented the case by memory, her gaze focused on the General's unsmiling face.
