+=+ My opinion is that partnership history may corroborate. But
the most cogent evidence is the actions of the partner and the 
partnership after the aberrant action; if the subsequent action is 
*abnormal* and *caters for the possibility of the psyche* it is prima 
facie evidence of collusion and requires to be explained convincingly.
