I shall be in the second cubicle in the ladies in the airport on Muckle Flugga at 8.37 pm on the 29th Feb. The password is "The grey owl hoots at 1 am", and the answer is, "Marks and Spencer have purple shape-huggers for £10.99". Slide the micro-film under the door and leave by the trap-door above the fifth cubicle. The top secret papers are behind the urinal in the gents. The submarine will not wait. If you are not there by 9.07 pm it will sail without you. The papers must not be found on you, if you are arrested, eat them.
