It is time to find the password that the intruder used to gain entry to the secret passage, so light a fag, pour yourself a whisky, put on your flared trousers and kipper tie and tell the person next to you to ‘Shut it!’.

After the intruder had helped himself to my Ian Fleming collection, he left the Library and made his way past the Dining Room and stopped to examine a rather handsome African warrior mask that is mounted on the wall opposite the Armoury.

Quentin had informed him that if he spoke two specific words into the mouth of the mask, a secret door would open revealing a passage leading to The Small Room, where other ‘treasures’ are kept.

Now, please pay attention to what I am about to tell you.

The passwords contain 7 and 4 letters, respectively.

Decide what the following letters all have in common to give you a clue:

JRJT GCDW FHGM

Remember, I must have the passwords as well as what the letters represent, plus an explanation as to how you came to your conclusion. Single word answers or incomplete explanations will be ignored and will only help your rival detectives, so please do not post any answers before you are sure you have cracked it.

Good luck, everyone.
