一起不可能發生的密室兇殺案…… 一個瀕臨崩潰邊緣的飯店警衛…… 將使時空旅行的存續，變得岌岌可危 January Cole在一間專門接待時空旅行遊客的豪華飯店Paradox裡擔任警衛。據傳，時空轉換之處亦是鬼魂逗留之處，而沒有人比January更清楚此事，只因她是唯一看得到526號房裡陰魂不散鬼魂的那個人…… 當美國政府即將開放時空旅行私營化傳言一起，Paradox飯店內霎時間冠蓋雲集，一個個摩拳擦掌準備分一杯羹的企業家都在此聚首。然而，當暫居飯店內商業鋸子開始發生令人不解的神秘「意外」，January的通靈體質，能否順利協助她找出兇手？亦或會將她推往心神失序的邊緣？ An impossible crime. A detective on the edge of madness. The future of time travel at stake. From the author of The Warehouse . . . January Cole’s job just got a whole lot harder. Not that running security at the Paradox was ever really easy. Nothing’s simple at a hotel where the ultra-wealthy tourists arrive costumed for a dozen different time periods, all eagerly waiting to catch their “flights” to the past. Or where proximity to the timeport makes the clocks run backward on occasion—and, rumor has it, allows ghosts to stroll the halls. None of that compares to the corpse in room 526. The one that seems to be both there and not there. The one that somehow only January can see. On top of that, some very important new guests have just checked in. Because the U.S. government is about to privatize time-travel technology—and the world’s most powerful people are on hand to stake their claims.
