The Mysterious Story Of The Gibbons Twins
Placed on high doses of antipsychotic medications, they found themselves unable to concentrate; Jennifer apparently developed tardive dyskinesia (a neurological disorder resulting in involuntary, repetitive movements). Their medications were apparently adjusted sufficiently to allow them to continue the copious diaries they had begun in 1980, and they were able to join the hospital choir, but they lost most of their interest in creative writing. The case achieved notoriety due to newspaper coverage by journalist Marjorie Wallace of The Sunday Times. Wallace later wrote a book about the two titled The Silent Twins, published in 1986 by Prentice Hall.
