BBB:

A very good retelling of the stories of Patin and Caramouche. Many great
betting scams have come unraveled due to an unlikely winning margin. In one of
my favorites, a trainer was able to enter a 3YO in a race restricted to 2YOs in
England. The scam may have gone undetected were it not for a gaudy winning
margin of 20 lengths...in a five furlong race.

In the early 80s, a full field of 12 faced the starter in a 6 furlong dash at
the Fairgrounds. The starter made an announcement to the jockeys that the
stewards stand had called, and that the stewards had reason to believe that one
of the riders in the race was carrying a battery. The starter announced that
there would be no further investigation if the rider dropped the battery in the
starting gate before the race began.

After the field broke from the gate, the assistant starters were mildly
surprised to find no less than 7 batteries on the ground.
