He must have stood on it to reach the ventilation window.

他一定站在上面才能到达通风窗。

我还没来得及思考他的举动，通风窗里就出现了一丝光亮。

" " The bell rope worked like a bridge between the ventilation window and the bed.

” “铃绳就像通风窗和床之间的一座桥梁。

Of course, when we discovered the ventilation window that connected Roylott's room to Julia's, I was convinced a snake was the murder weapon.

當然，當我們發現連接羅伊洛特房間和茱莉亞房間的通風窗時，我確信蛇是殺人武器。

However, last night, when I frightened the snake with the lit match, it retreated back up the bell rope and through the ventilation window before Roylott expected.

然而，昨晚，当我用点燃的火柴吓跑蛇时，它在罗伊洛特预料之前就退回了铃绳并穿过通风窗。

Roylott must have trained the snake to climb through the ventilation window and down the bell rope onto the bed, which, you will recall, was bolted to the floor.

罗伊洛特一定训练过蛇爬过通风窗，顺着铃铛绳爬到床上，你会记得，床是用螺栓固定在地板上的。
