Set a large pot of water to boil, and salt it well.
In a small saucepan, warm the olive oil, garlic, and pepper over low heat until the garlic turns golden brown.
Add the crab, salt, pepper, and wine, and simmer until reduced slightly.
Add half the parsley, cook another minute, and turn off the heat.
Cook the pasta according to the package instructions.
When it is just about done, reheat the crab sauce.
Drain the pasta, toss with the sauce, and top with the remaining parsley.
