happened？'
'Major Webb was to meet his car at twenty…three…hundred hours on the corner of Lexington and Seventy…second Street。 The time was firm； but he didn't show up。 By twenty…three…thirty the driver became alarmed because of the distance to the airfield in New Jersey。 The sergeant remembered the address … mainly because he'd been told to forget it … drove round and went to the door。 The security bolts had been jammed； and the door just swung open； all the alarms had been shorted out。 There was blood on the foyer floor； the dead woman on the staircase。 He walked down the hall into the operations room and found the bodies。'
'That man deserves a very quiet promotion；' said the naval officer。
'Why do you say that？' asked the senator。 Crawford replied。 'He had the presence of mind to call the Pentagon and insist on speaking with covert transmissions； domestic。 He specified the scrambler frequency； the time and the place of reception； and said he had to speak with the sender。 He didn't say a word to anyone until he got me on the phone。'
'Put him in the War College； Irwin；' said Conklin grimly； holding his cane。 'He's brighter than most of the clowns you've got over there。'
That's not only unnecessary； Conklin；' admonished the senator； 'but patently offensive。 Go on； please； General。'
Crawford exchanged looks with the C。I。A。 man。 I reached Colonel Paul McClaren in New York； ordered him over there； and told him to do absolutely nothing until I arrived。 I then phoned Conklin and George here； and we flew up together。'
'I called a Bureau print team in Manhattan；' added Conklin。 'One we've used before； and can trust I didn't tell them what we were looking for； but I told them to sweep the place and give what they found only to me。' The C。I。A。 man stopped； lifting his cane in the direction of the naval officer。 Then George fed them thirty…seven names； all men whose prints we knew were in the F。B。I。 files。 They came up with the one set we didn't expect； didn't want。。。 didn't believe。'
'Delta's；' said the senator。
'Yes；' concurred the naval officer。 The names I submitted were those of anyone … no matter how remote … who might have learned the address of Treadstone； including； incidentally； all of us。 The room had been wiped clean； every surface； every knob； every glass … except one。 It was a broken brandy glass； only a few fragments in the corner under a curtain； but it was enough。 The prints were there： third and index fingers； right hand。'
'You're absolutely positive？' asked the senator slowly。
'The prints can't lie； sir；' said the officer。 They were there； moist brandy still on the fragments。 Outside this room； Delta's the only one who knows about Seventy…first Street'
'Can we be sure of that？ The others may have said something。'
'No possibility；' interrupted the brigadier…general。 'Abbott would never have revealed it and Elliot Stevens wasn't given the address until fifteen minutes before he got there； when he called from a phone booth。 Beyond that； assuming the worst； he would hardly ask for his own execution。'
'What about Major Webb？' pressed the senator。
The major；' replied Crawford； 'was radioed the address by me after he landed at Kennedy Airport As you know； it was a G…Two frequency and scrambled。 I remind you； he also lost his life。'
'Yes； of course。' The ageing senator shook his head。 'It's unbelievable。 Why？'
'I should like to bring up a painful subject；' said Brigadier…General Crawford。 'At the outset； I was not enthusiastic about the candidate。 I understood David's reasoning and agreed he was qualified； but if you recall； he wasn't my choice。'
'I wasn't aware we had that many choices；' said the senator。 'We had a man … a qualified man； as you agreed … who was willing to go in deep cover for an indeterminate length of tune； risking his life every day； severing all ties with his past How many such men exist？'
'We might have found a more balanced one；' countered the brigadier。 'I pointed that out at the time。'
'You pointed out；' corrected Conklin； 'your own definition of a balanced man； which I； at the time； pointed out was a crock。'
'We were both in Medusa； Conklin；' said Crawford； angrily yet reasonably。 'You don't have exclusive insight。 Delta's conduct in the field was continuously and overtly hostile to mand。 I was in a position to observe that pattern somewhat more clearly than you。 '
'Most of the time he had every right to be。 If you'd spent more time in the field and less in Saigon you would have understood that。 I understood it。'
'It may surprise you；' said the brigadier； holding his hand up in a gesture of truce； 'but I'm not defending the gross stupidities often rampant in Saigon； no one could。 I'm trying to describe a pattern of behaviour that could lead to the night before last on Seventy…first Street。'
The C。I。A。 man's eyes remained on Crawford； his hostility vanished as he nodded his head。 'I know you are。 Sorry。 That's the crux of it； isn't it？ It's not easy for me； I worked with Delta in half a dozen sectors； was stationed with him in Phnom…Penh before Medusa was even a gleam in the Monk's eye。 He was never the same after Phnom…Penh； it's why he went into Medusa； why he was willing to bee Cain。'
The senator leaned forward on the couch。 〃I've heard it； but tell me again。 The President has to know everything。'
'His wife and two children were killed on a pier in the Mekong River； bombed and strafed by a stray aircraft … nobody knew which side's … the identity never uncovered。 He hated that war； hated everybody in it He snapped。' Conklin paused； looking up at the brigadier。 'And I think you're right； General。 He snapped again。 It was in him。' 'What was？〃 asked the senator sharply。 The explosion； I guess；' said Conklin。 The dam burst He'd gone beyond his limits and the hate took over。 It's not hard； you have to be very careful。 He killed those men； that woman； like a madman on a deliberate rampage。 None of them expected it； except perhaps the woman who was upstairs and probably heard the shouts；。。 He's not Delta any more。 We created a myth called Cain； only it's not a myth any longer。 It's really him。'
'After so many months。。。' The senator leaned back； his voice trailing off。 'Why did he e back？ From where？'
'From Zurich；' answered Crawford。 'Webb was in Zurich and I think he's the only one who could have brought him back。 The 〃why〃 we may never know unless he expected to catch all of us there。'
'He doesn't know who we are；' protested the senator。 'His only contacts were the Yachtsman； his wife and David Abbott。'
'And Webb； of course；' added the general。
'Of course；' agreed the senator。 'But not at Treadstone； not even him。'
'It wouldn't matter；' said Conklin； tapping the rug once with his cane。 'He knows 〃there's a board； Webb might have told him we'd all be there； reasonably expecting that we would。 We've got a lot of questions … six months' worth； and now several million dollars。 Delta would consider it the perfect solution。 He could take us and disappear。 No traces。'
'Why are you so certain？'
'Because； one； he was there；' replied the intelligence man； raising his voice。 'We have his prints on a glass of brandy that wasn't even finished。 And； two； it's a classic trap with a couple of hundred variations。'
'Would you explain that？'
'You remain silent；' broke in the general； watching Conklin； 'until your enemy can't stand it any longer and exposes himself。'
'And we've bee the enemy？ His enemy？'
There's no question about it now；' said the naval officer。 'For whatever reasons； Delta's turned。 It's happened before thank heaven； not very often。 We know what to do。'
The senator once more leaned forward on the couch。 'What will you do？'
'His photograph has never been circulated；' explained Craw…ford。 'We'll circulate it now。 To every station and listening post； every source and informant we have。 He has to go somewhere； and he'll start with a place he knows； if only to buy another identity。 He'll spend money； he'll be found。 When he is； the orders will be clear。'
'You'll bring him in at once？'
'We'll kill him；' said Conklin simply。 'You don't bring in a man like Delta； and you don't take the risk that a
