At that adjoining me, a tall, swarthy individual, with close-cropped hair, an Italian without doubt, was seated.

He glanced at me as I took my place, and then continued his meal as if he were unaware of my presence in the room.
By the time I had finished my lunch I had thoroughly impressed his face and personality upon my memory, and felt sure that, if necessary, I should know him anywhere again.

My labours, however, were by no means over; in fact they were only just beginning.

What I had against him so far would scarcely be sufficient to justify our applying for a warrant for his arrest.

If I wanted to bring the crime home to him, it would be necessary for me to connect him with it more closely than I had yet done.
