　　Bond had walked for only a few minutes when it suddenly occurred to him that he Wasbeing followed．There was no evidence for it except a slight tingling(隐隐作痛)of the scalp(头皮)and an extra awareness ofthe people near him，but he had faith in his sixth senseand he atonce stopped in front of the shop window he Was passing and looked casually back along 46thstreet．Nothing but a lot ofmiscellaneous people moving slowly on the sidewalks, mostly on the same side ashimself ,the side that was sheltered from the sun．ThereWas no sudden movementinto a doorway,．nobody casuallywiping his face with a handkerchief to avoid recognition，nobody bending down to tie a shoelace．
　　Bondexamined the Swiss watches in his shop window and then turned and sauntered on.After a few yards he stopped again．Still nothing．He went onand turned right into the Avenueof the Americans．stoppingin the first doorway，the entrance to a women’sunderwear store where a mall in a tan suit with his back to him was examiningthe black lace‘pants on a particu—laxly realistic dummy(模型)．Bond turned and leant against a pillar andgazed lazily but watch-fully out into the street．
　　And then something gripped his pistol arlnand a voice snarled：“All fight，Limey．Takeiteasy unless you want lead for lunch”，and he feltsomething press into his back just above thekidney．
What wa$there familiar about that voice?Thelaw?The gun?Bond glanced down to seewhat Was holding his right ann．It Was a steel hook．Well．if the man had only onearm!Likelightening he turned around，bending sidewaysand bringing his left fist round in a flailingblow，lowdown．
　　There was a smack as his fist was caught inthe other mail'S left hand．and at the 881Tle time asthe contact telegraphed to Bond's mind thatthere could have been no gun，there came thewell-re-membered laugh and the lazy voice saying：“Nogood．James．The angles have gotyou．”
　　Bond straightened himself slowly and for amoment he could only gaze into the grinninghawk．life face of FelixLeiterwith blank disbelief，his builtup tension slowlyrelaxing．
　　“So you were doing a fmnt tail，you lousy bastard，”he finally said．
