With regards to Lennons odds. Judging by Boyle sports price I would guess they had a sizeable bet placed. The other bookies would have followed suit in bringing his price in. They can't afford to bring the odds back out in case the initial guy was in the know and another sizeable bet is placed. Better to just take him out of the market and keep his price down then run the risk.
Same thing would happen if a 100/1 shot in a small race had a large bet placed on it. They would bring the odds in to take it out of the market incase someone is in the know. Not worth risking it for afew extra £10 bets at a big price.
Sorry, don't want to sound like a know it all, I just like a bet and I would guess that's what's happened so thought I would offer my opinion.
