The Way Of the Travelling Lemon

Greetings, oh seeker after the Way of the Travelling Lemon. Here are the locations of the ten lemons hidden in the photos of the crew's desks:

ARTHUR

1. One of Arthur's notebooks has the word ‘Lemon’ printed on the back. If you didn't spot this one, to be honest, the life of a professional lemon-hunter may not be for you.
2. Arthur's phonetic alphabet guesses are nearly all almost right... but not quite. His guess for 'L' is hidden by the strap. The correct answer is 'Lima'. What do you suppose he guessed? (Bonus points for noticing which letters Arthur always gets right, and working out why...)

DOUGLAS

1. Poor old Captain Crieff can't even win at hangman. Even when the word Douglas picked is one you'd think he would never forget.
2. This is a sneaky one, as you would expect from Douglas. But if you look at his notes of some of the friends he's made on his travels; brown-haired Liz from New York who works in television may seem familiar to viewers of '30 Rock'...

MARTIN

1. If you study the manual as closely as Martin would wish you to do, you will notice that it's apparently vital that the L.E.M is... ON.
2. Martin’s phone number on his Icarus business card is oddly formatted for a British number. You don't suppose that each pair of numbers could stand for a letter of the alphabet, do you? As in, 01 is A, 02 is B ... 12 is L, 05 is E, 13 is M...

CAROLYN

1. Snoopadoop sports the latest in lemon-shaped neckwear.
2. Carolyn drives a Citroën, apparently. And Citroën is Dutch for...

HERC

1. Some of those strange vegetarian ingredients aren’t as exotic as Carolyn thinks. 'Ning Meng', for instance, has another, more citrussy, name.
2. When Yverdon LE Bains meets MONday, the lemon is in play.

There is an eleventh lemon hidden somewhere in this box set as well - but if you haven't found it yet, perhaps you haven't listened to enough of the show...
