The last word echoed in Trobin's ears after he had stepped from the car. He was repeating "fifth" aloud,
as he heard the door clang behind him. Then, Trobin's lips tightened into an actual smile; his eyes took on
a shrewd glisten. The operator had made a mistake, letting him off at the fifth instead of the sixth floor. It
was a mistake that pleased Mark Trobin.
He was picturing his corner room, on the floor above; how he could reach it secretly and do his packing,
unnoticed by any lurkers who might be watching. After that, he could leave the room in the same manner,
and simply send up for his luggage.
No one would ever know that he, Mark Trobin, had gone in and out. Pleased with his smartness, Trobin
was sure that he could outfox any vigilant Chinese who might be on his trail.
Just what results Trobin's smart idea was to bring him, the next ten minutes were destined to tell!
CHAPTER II. CROSSED TRAILS
EYES were watching the hallway outside of Trobin's sixth-floor room, at the Hotel Esplanade.
They were eyes that burned from darkness; the eyes of a shrouded, unseen observer, black-cloaked and
hatted, whose own post was within the room next to Trobin's, on the left. Those eyes were peering
through the crack of the door, so slightly opened that the space was almost imperceptible.
The watcher was The Shadow.
Talk of a mysterious stir in San Francisco's Chinatown, confined to certain Chinese of whom but little
was known, had been enough to bring The Shadow to this city of the Golden Gate. Coupled to that, he
had learned that thuggish Americans were abroad in Frisco. Bad elements, both: unknown Chinese, and
known Americans.
The Shadow had learned that with different races, certain symptoms were in opposition. He was
interested, therefore, in learning what each of these small, but dangerous, groups could be after.
Across the hall, in the room to the right of Trobin's but looking out on another side of the hotel, was a
second watcher. He was Harry Vincent, a competent young man who happened to be one of The
Shadow's agents.
Harry knew that The Shadow had picked up a trail from Chinatown, and followed it to the Hotel
Esplanade. Whatever the trail meant, it had much to do with Mark Trobin, the man who had taken the
corner room on the sixth floor, but who, very fortunately, was at present absent.
Very fortunately, because someone else was in the room. Watching from his window, Harry had seen a
writhy figure, a Chinese, climb up from a balcony below and enter Trobin's room, only a half hour ago.
Harry had reported that fact to The Shadow, by a signal from his own door.
At present, Harry was watching to see if anyone else would arrive. It was possible that the entrant was
but the forerunner of others. As for Trobin, who might be due back at any time, he wasn't Harry's
concern. Trobin would naturally enter by his own door, which The Shadow was watching. The Shadow,
of course, intended to flag Trobin before the fellow could come to any harm.
Darkness had settled half an hour ago, at the time when the snaky Chinaman had entered Trobin's room.
Both balconies, the one outside Trobin's window and that of the fifth floor just beneath, were visible, but
Harry found it difficult to watch them.
His eyes were constantly attracted by the distant gleam of lights, lurid sparkles tinged with many colors,
