She paused and looked back over her shoulder as a Bristol fighter roared its way into the sky behind them and made its patient and pointless way north-west over the Khyber. ‘Good old Fred! That’ll keep them guessing!’ Her tone changed. ‘Once we’ve been admitted to the fort the nature of the game changes. You, I and the two boys will have become their guests and thereby under their protection. It ought to work but I’d be more comfortable if – just in case it doesn’t and, as the saying goes, “the worst came to the worst” – you had one of these.’ She reached across as he rode beside her and put a red glass capsule in his hand. ‘Cyanide,’ she said and continued, ‘I expect I’m being histrionic but there is just a chance – more than a chance – that this could go wrong.’ She gave him a level glance and resumed, ‘Put it where you can easily get at it.’
‘It’s glass,’ said Joe, momentarily puzzled.
‘Should you be in a position where you need to use it, a mouth full of glass will be the least of your problems!’
Joe pondered the implication, saying at last, ‘Believe me, Grace, I don’t want to be there when it goes wrong but if it does I’ll just carry on taking the tablets and see you in a fortnight. Correct?’
‘Yes, that’s about it.’
The easy way in which Grace handed out a lethal poison reawakened all Joe’s suspicions. The scene might have changed into a desperate rescue dash into the hills to bring out Rathmore and Lily but his main objective remained to find out who had killed Zeman. He was sure that much would flow from that solution. He had never accepted the theory of andromedotoxin poisoning that Grace had put forward and was even less happy with the idea of a fatal dose of arsenic delivered through the medium of the unfortunate pheasant and, what was more, he knew Grace could never have subscribed to these theories either. Achmed’s so fortuitously timed confession had played innocently into her hands but he found he was left with the inevitable conclusion that Grace was involved in a cover-up, a cover-up in which she had been caught out by Iskander. But for the midnight swim, all would have been happy or at least accepting of the arsenic theory. But for whom was she covering? Herself? James? Iskander? Someone else?
He imagined the pressure on Grace as she had performed her autopsy with a Scotland Yard detective present and all too literally sticking his nose in. Her sangfroid was amazing and, surely, could only, in a woman of such high principles, stem from a perfectly clear conscience? He decided to take advantage of their present circumstances to put further pressure on her. Out here she could not evade his questioning.
‘There’s a lot riding on this expedition,’ Grace was saying. ‘I don’t put these things in any order of priority but we have to extricate that damn fool Rathmore and we have to winkle out Lily.’
‘How easy you make it sound,’ said Joe, ‘but have you paused to consider that, whereas Rathmore undoubtedly was kidnapped, Lily may well have gone off with Iskander of her own accord? Lord knows why! A yearning for adventure? Spoilt little madam whose head’s been turned by too many moving pictures? An admirer of Rudolph Valentino perhaps? Perhaps she’s simply inherited her father’s enterprising spirit? I gather Coblenz senior is a financial pirate of the first water who, in his time, has gobbled up half the resources of the West.’
‘And perhaps his daughter is now making a play for the East?’ said Grace. ‘No. She has her faults but treachery and stupidity are not among them. She’s clever and, I do believe, good-hearted. No. I’m sure she was forced or tricked in some way into going with them. If she went at all willingly – and this I don’t believe – it would be on account of her feelings for Iskander.’
Joe reined in his horse in surprise. ‘Feelings for Iskander? Grace, what are you saying? Lily was flirting with both young men and – goodness! – one sees why! But, if anything, she showed more interest in Zeman!’ Joe carefully kept back the revelation that Lily had attempted to meet him in the garden. Once again he had the strong impression that he was fencing with Grace, always feinting and falling back, hoping to lure her into making a false step.
‘Oh, Joe! You don’t know much about girls, do you? Look – girls of Lily’s age regularly take an indirect route to claim the attention of the one they’re really interested in. This is why “best friends” are so useful! By scintillating – I think Lily would call it “sparking” – with Zeman she was actually showing herself off to Iskander who was always there, as I’m sure you noticed, a ready audience.’
