"Mark Phillips" is, or are, two writers: Randall Garrett and Laurence M. Janifer. Their joint pen-name, derived
from their middle names (Philip and Mark), was coined soon after their original meeting, at a science-fiction
convention. Both men were drunk at the time, which explains a good deal, and only one has ever sobered up.
A matter for constant contention between the collaborators is which one.
They have been collaborating for some time now, and have devised an interesting method of work: Mr.
Garrett handles the verbs, the adverbs and the interjections, Mr. Janifer the nouns, pronouns, and adjectives.
Conjunctions are a matter of joint decision, and in the case of a tie, the entire game is replayed at Fenway
Park, Boston, early in the following year.
BRAIN TWISTER was fifteen years in the making, of which time three days were spent in the actual writing.
When the book was finished, both authors relaxed in the mutual pleasure of nervous breakdowns, from which
it is not certain that either has ever recovered.
Mr. Garrett is a large, roundish fellow with a beard. He wears flowered vests and always carries a small
talisman which no one has ever seen. Mr. Janifer is a somewhat shorter and thinner type, with a shorter and
thinner beard. His vests are in solid colors, he wears horn-rimmed glasses because he has always done so, and
he is never found without a souvenir subway token from the City of New York.
The personal lives of the authors differ widely. Mr. Garrett's hobbies, for instance, include such sports as
close-order drill and river pollution. Mr. Janifer, a less active type, prefers sedentary games such as humming
Mr. Garrett is engaged to an exotically beautiful creature, and the two plan to be married as soon as they run
out of excuses. Mr. Janifer, on the other hand, is fascinated by women, and hopes some day to meet one.
