54 Look for 8 consecutive letters in the clue!

89 The correct spelling should be "barbeCue". This is essential for the clue to work!

54. It's a prison, I think in New York, and it's contained in the question

Many thanks johnalex, crofter and FoxLee - so easy when the answers are pointed out.
Great help, thanks again.

Can anyone help me with no 55 please? Start working without Mr Sumner and produce the graphics (7). This is the only answer I have left to find (not sure if they are all righty!,) apart from the squirrel one which seems to have everyone stumped!

[Chrysaor]

Wymondham2, I have artwork for 55 (start working minus Sting) but would appreciate any hints on the following, which I'm sure everyone else has:

99. The meaning of Junction 42 sounds more cha-cha (3,3,3)

5. Nips back to a small lie that returns with mixed aid for birth defect (5,6)

[Chrysaor]

I've just worked out 99...

[x-ray]

5 is spina bifida

[crofter]

Chrysaor "nips"gives "spin" which starts a particular birth defect?

[FoxLee2]

To dot the is and cross the ts - with No.5 - small lie is fib (returns becomes bif) and then mixed with aid to give bifida.

Some of these clues are so clever - we only have to solve them, someone had to come up with the questions.

[Chrysaor]

Thanks a lot to all who answered my query!

[Chrysaor]

Now my problem is that the introduction says that the letters 'two' appear in 20 of the answers and I can find it in 21. Did anyone else find the same?

[x-ray]

Chrysaor,
My answer to 20 has the letters TWO in the middle

[x-ray]

Sorry I misread yoyr question.
I think 21 is definately ROMULUS AND REMUS though

[x-ray]

Oh, I see what you mean now. That is interesting, never saw that statement....means something is wrong somewhere. Oh dear !!!!!

[Chrysaor]

I've got a feeling we're barking up the wrong tree about 31. The answer I have does have 'two' in it but I feel the whole word possibly means 'an operator' and it doesn't exactly. That may be where my extra one came from. I have no other ideas though!
