They entered the world just five minutes apart, twins swimming out of the womb together, already arguing about who got to lead the way. They grew up together, best friends with rhyming names. They even went to the same college — where one of them had a nervous breakdown, and the other didn't. Grown-up, one of them became a suicidal drunk, the other a success. Now, one is missing, and the other has just three days to find him. It really happened. The History of Swimming details Kim Powers' frantic search for his twin brother Tim who disappears from Manhattan one weekend while in his late 20s. Kim almost mystically imagines that the clues to Tim's whereabouts have been planted in a series of letters written by Tim over the years. Now, Kim uses the letters as a sort of roadmap that takes him to Texas, the setting of their greatest triumphs and tragedies. At the small Texas college where many of these events occurred, Kim falls in with two eccentric traveling companions who guide him on the last leg of his quest, driving through the night to the one final place where Tim might be.
