In a new advert on February 25, 1893 in the Illustrated London News, Mr. Roe cunningly turned the whole lost case to his advantage. He described the culpable advert, and then said,

"Many thousand Carbolic Smoke Balls were sold on these advertisements, but only three people claimed the reward of £100, thus proving conclusively that this invaluable remedy will prevent and cure the above mentioned diseases. The CARBOLIC SMOKE BALL COMPANY LTD. now offer £200 REWARD to the person who purchases a Carbolic Smoke Ball and afterwards contracts any of the following diseases..."

Some people, in over their heads, seem to insist that there's no hole at all.

I'm pretty sure we know more now.
