In this article the complex variable theory of two-dimensional Stokes flow as developed by Richardson [22], and modified by Howison Richardson [16], is reviewed. The analysis of [16] is extended to a new solution driven by a point sink, which uses a cubic polynomial conformal mapping (with real coefficients) from the unit disk onto the fluid domain. This solution is analysed in the limit of small surface tension. An apparent 'stability paradox' (where two equivalent flow geometries are found, one of which is 'stable' and the other unstable) is resolved by allowing the coefficients to take complex values.
