the Grecian bend. This led to the nickname âthe bends.â Given the depth at which they were currently working, Crane felt certain caisson disease was involved one way or another.
âI assume you have a hyperbaric oxygen therapy chamber or some other kind of recompression equipment on site youâve been treating the patients with?â he asked. âWhen weâre done here, Iâd like to question them directly, if you donât mind.â
âActually, Doctor,â Bishop said in a clipped voice, âI think we could proceed more quickly if you let me outline the symptomology, rather than make assumptions.â
This took Crane by surprise. He looked at her, unsure why she had responded so tartly. âSorry if Iâm overeager or presumptuous. Itâs been a long trip, and Iâm very curious. Go right ahead.â
âWe initially became aware something was wrong about two weeks ago. At first it seemed more a psychological issue than a physiological one. Roger noticed a spike in the number of walk-in visits.â
Crane glanced at Corbett. âWhat were the symptoms?â
âSome people complained of sleep disturbances,â Corbett said. âOthers, malaise. A few cases of eating disorders. The most common complaint seemed difficulty in focusing on what they were doing.â
âThen the physical symptoms began,â Bishop said. âConstipation. Nausea. Neurasthenia.â
âAre people working double shifts down here?â Crane asked. âIf so, Iâm not surprised theyâre feeling fatigued.â
âOthers complained of muscle tics and spasms.â
âJust tics?â Crane asked. âNo associated pain?â
Bishop looked at him with mild reproach, as if to say,
If there had been pain, I would have mentioned it, wouldnât I?
âThese people arenât presenting with caisson disease,â Crane said. âAt least, no variant Iâm aware of. I guess I donât see the concern. Problems with concentration or focus, constipation, nauseaâ¦thatâs all non-specific. It could simply be work-induced stress. Itâs an unusual environment and an unusual assignment, after all.â
âIâm not through,â Bishop said. âOver the last week, the problems have grown worse. Three cases of cardiac arrhythmia in people with no history of heart disorders. A woman with bilateral weakness of the hands and face. And two others suffered what appeared to be transient ischemic attacks.â
âTIAs?â Crane said. âHow extensive?â
âPartial paralysis, slurred speech, lasting in each case less than two hours.â
âWhat were their ages?â
âLate twenties and early thirties.â
âReally?â Crane frowned. âThat seems awfully young for a stroke.
Two
strokes, at that. You did neurological workups?â
âDr. Crane, please. Of
course
we did neurological workups. Non-contrast cranial CT scans; EKGs to check for cardioembolic event triggers; the rest. Thereâs no EEG on the stationâyou know theyâre mainly used for seizure disorders or comaâbut in any case it wasnât necessary here. Except for evidence of stroke,
everything
was completely normal.â
Once again the tartness had crept into her tone.
Sheâs territorial,
Crane thought.
This is her turf and she doesnât like me stepping on it.
âEven so,â he said, âitâs the first evidence of dysbarism Iâve heard today.â
âDysbarism?â Corbett asked, blinking through his round glasses.
âDecompression sickness. Caisson disease.â
Bishop sighed. âActually, I believe that caisson disease is the one thing we can safely rule out.â
âWhy? I assumedââ Crane fell silent. He realized that Asher had never told him outright what the problem was. Given the nature of the Deep Storm station, heâd assumed caisson
