Geometry Problem 1321: Intersecting Circles, Diameter, Secant, Chord, Collinearity

Two circles with centers O and Q intersect at points E and F. AB and CD are diameters of circles O and Q, respectively. AC cuts the circles Q and O at G and H, respectively. BD cuts the circles Q and O at J and K. AK cuts DG at L. BH cuts CJ at M. Prove that the points F, L, M, and E are collinear.
