We are now four episodes into the Channel 4 series Hunted and contestants continue to drop like flies.

Newcomer Adam Young was given a baptism of fire, zig-zagging up and down the country before he was eventually caught getting off a coach.

Friends Lauren and Emily remained at large after separating from each other last week, with Stephen and Martin surviving an early scare to also remain untracked in the wilderness.

The Hunters were tweeting throughout the show, letting the fugitives know they were never far behind.

Here is what we learned from week four of Hunted.

1. A single sheep is called a sheep

Walsall lads Stephen and Martin started the show with an impressive display of rural ignorance, when Stephen asked his companion what a single sheep is called.

It confused us too.

2. You don’t need money when you have skills

Stephen and Martin showed their initiative, however, by securing a pair of bicycles for free, in exchange for a quick bit of plumbing work.

They may have got themselves bikes, but you should never forget about the man behind the lens.

3. Watch what you search for

The Walsall pair’s plan of cycling along canal routes seemed foolproof, until they decided to head to a caravan the Hunters had already caught wind of.

Website cookies led to the Hunters intercepting a series of emails advertising properties in Wales, which the pair had been looking at online.

4. People really, really, need to stop phoning home

People couldn’t help but notice that virtually every contestant so far cannot resist phoning, or at very least trying to contact, home.

In the event of another series, we hope the next batch of contestants are a bit more heartless than the current lot – they might last longer.

5. ALWAYS tip the waitress

Adam, who said he was once the “only gay in the village” in his hometown, chose a different tack while on the run – camping in the wilderness.

His plan hit complications after a media campaign was launched against him, meaning his decision not to tip a waitress led to her phoning the Hunters.

6. Apparently blind prejudice is a core skill for any detective

One of the Hunters decided he would pursue a lead almost exclusively on the basis that someone looked a bit dodgy.

Standards are seriously slipping in Scotland Yard if this is how detectives are getting trained up.

7. Public transport will inevitably be your downfall on this show.

After a number of narrow escapes in Yorkshire and Edinburgh, Adam’s spell as a fugitive came to an end when he was spotted on CCTV getting on a coach.

The number of contestants getting caught after hopping on to a coach or a bus is growing by the week.

The person to conquer this show will be the one who keeps clear of the Megabus.

8. We are still mourning the loss of Ricky Allen

Ricky Allen stole the hearts of the nation after outwitting the Hunters for three episodes, before eventually being caught last week.

His great mind and wry sense of humour were missed in this week’s instalment.
