Letter: `Mythical' raccoon spotted in Boston

Sir: Mary Dejevsky says of raccoons: "these endearing but villainous animals are just another component of the American myth . . . the truth is that they do not exist." ("The great suburban sinner who has gone to ground", 4 August).

I have never yet photographed a unicorn successfully, but Ms Dejevsky may like to see this photograph of the "mythical" raccoon taken from a second-floor window in Monument Square, Charlestown, Boston, Massachusetts, at 7.30am on the morning of 15 July this year. He was seated on an old fire escape which stops at first-floor level, some 12 feet above the ground.

I wonder if any reader can advise me on the best time of day to see a unicorn?
