Query: Drowsy Cheetah Hunting Antelopes: A Diffusing Predator Seeking Fleeing
  Prey   We consider a system of three random walkers (a `cheetah' surrounded by two
`antelopes') diffusing in one dimension. The cheetah and the antelopes diffuse,
but the antelopes experience in addition a deterministic relative drift
velocity, away from the cheetah, proportional to their distance from the
cheetah, such that they tend to move away from the cheetah with increasing
time. Using the backward Fokker-Planck equation we calculate, as a function of
their initial separations, the probability that the cheetah has caught neither
antelope after infinite time.
