Preheat oven to 425 degrees F.

In small bowl, mix together sugar, flour, salt, nutmeg, egg, cream, and vanilla. Place peach slices in large bowl and gently pour sugar/flour mixture over, stirring to blend. Pour gently into unbaked 9" pie crust.

Make topping by first combining sugar, flour, and cinnamon, and then cutting in the butter until crumbly. Do not put the topping on the pie yet.

Bake the pie at 425 degrees F for 15 min. Reduce heat to 325 degrees F, and bake 25 minutes more.

Sprinkle with crumb topping and immediately return to oven for another 15 min, or until bubbly near center.

Allow pie to cool until just slightly warm before serving. Refrigerate any leftovers.
