Greenwich Maths Challenge 3

The following text has been encrypted with a Vigenere cipher. (Simon Singh's Code Book CD-rom, which can be downloaded free, has a useful tool for deciphering such ciphers.) The text which has been enciphered contains one number which has been omitted. The prize for this challenge will be awarded to the first Greenwich maths undergraduate to email to A.Mann@gre.ac.uk two pieces of information: 1) the missing number and 2) the Vigenere keyword.
